When columns are set to automatic for git tag and the output is
paginated by git, the output is a single column instead of multiple
columns.
Standard behaviour in git is to honor auto values when the pager is
active, which happens for example with commands like git log showing
colors when being paged.
Since ff1e72483 (tag: change default of `pager.tag` to "on",
2017-08-02), the pager has been enabled by default, exposing this
problem to more people.
finalize_colopts in column.c only checks whether the output is a TTY to
determine if columns should be enabled with columns set to auto. Also
check if the pager is active.
Adding a test for git column is possible but requires some care to work
around a race on stdin. See commit 18d8c2693 (test_terminal: redirect
child process' stdin to a pty, 2015-08-04). Test git tag instead, since
that does not involve stdin, and since that was the original motivation
for this patch.

The previous patch taught `git tag` to only respect `pager.tag` in
list-mode. That patch left the default value of `pager.tag` at "off".
After that patch, it makes sense to let the default value be "on"
instead, since it will help with listing many tags, but will not hurt
users of `git tag -a` as it would have before. Make that change. Update
documentation and tests.

Using, e.g., `git -c pager.tag tag -a new-tag` results in errors such as
"Vim: Warning: Output is not to a terminal" and a garbled terminal.
Someone who makes use of both `git tag -a` and `git tag -l` will
probably not set `pager.tag`, so that `git tag -a` will actually work,
at the cost of not paging output of `git tag -l`.
Use the mechanisms introduced in two earlier patches to ignore
`pager.tag` in git.c and let the `git tag` builtin handle it on its own.
Only respect `pager.tag` when running in list-mode.
There is a window between where the pager is started before and after
this patch. This means that early errors can behave slightly different
before and after this patch. Since operation-parsing has to happen
inside this window, this can be seen with `git -c pager.tag="echo pager
is used" tag -l --unknown-option`. This change in paging-behavior should
be acceptable since it only affects erroneous usages.
Update the documentation and update tests.
If an alias is used to run `git tag -a`, then `pager.tag` will still be
respected. Document this known breakage. It will be fixed in a later
commit. Add a similar test for `-l`, which works.

Since we're about to change how `git tag` respects `pager.tag`, add tests
around this, including how the configuration is ignored if --no-pager or
--paginate are used.
Construct tests with a few different subcommands. First, use -l. Second,
use "no arguments" and --contains, since those imply -l. (There are
more arguments which imply -l, but using these two should be enough.)
Third, use -a as a representative for "not -l". Actually, the tests use
`git tag -am` so no editor is launched, but that is irrelevant, since we
just want to see whether the pager is used or not. Make one of the tests
demonstrate the broken behavior mentioned above, where `git tag -a`
respects `pager.tag`.

The previous patch introduced a way for builtins to declare that they
will take responsibility for handling the `pager.foo`-config item. (See
the commit message of that patch for why that could be useful.)
Provide setup_auto_pager(), which builtins can call in order to handle
`pager.<cmd>`, including possibly starting the pager. Make this function
don't do anything if a pager has already been started, as indicated by
use_pager or pager_in_use().
Whenever this function is called from a builtin, git.c will already have
called commit_pager_choice(). Since commit_pager_choice() treats the
special value -1 as "punt" or "not yet decided", it is not a problem
that we might end up calling commit_pager_choice() once in git.c and
once (or more) in the builtin. Make the new function use -1 in the same
way and document it as "punt".
Don't add any users of setup_auto_pager just yet, one will follow in
a later patch.

git.c: let builtins opt for handling `pager.foo` themselves
Before launching a builtin git foo and unless mechanisms with precedence
are in use, we check for and handle the `pager.foo` config. This is done
without considering exactly how git foo is being used, and indeed, git.c
cannot (and should not) know what the arguments to git foo are supposed
to achieve.
In practice this means that, e.g., `git -c pager.tag tag -a new-tag`
results in errors such as "Vim: Warning: Output is not to a terminal"
and a garbled terminal. Someone who makes use of both `git tag -a` and
`git tag -l` will probably not set `pager.tag`, so that `git tag -a`
will actually work, at the cost of not paging output of `git tag -l`.
To allow individual builtins to make more informed decisions about when
to respect `pager.foo`, introduce a flag DELAY_PAGER_CONFIG. If the flag
is set, do not check `pager.foo`.
Do not check for DELAY_PAGER_CONFIG in `execv_dashed_external()`. That
call site is arguably wrong, although in a way that is not yet visible,
and will be changed in a slightly different direction in a later patch.
Don't add any users of DELAY_PAGER_CONFIG just yet, one will follow in a
later patch.

blame: fix memory corruption scrambling revision name in error message
When attempting to blame a non-existing path, git should show an error
message like this:
$ git blame e83c51633 -- nonexisting-file
fatal: no such path nonexisting-file in e83c51633
Since the recent commit 835c49f7d (blame: rework methods that
determine 'final' commit, 2017-05-24) the revision name is either
missing or some scrambled characters are shown instead. The reason is
that the revision name must be duplicated, because it is invalidated
when the pending objects array is cleared in the meantime, but this
commit dropped the duplication.
Restore the duplication of the revision name in the affected functions
(find_single_final() and find_single_initial()).

We started using "%" PRItime, imitating "%" PRIuMAX and friends, as

Makefile: help gettext tools to cope with our custom PRItime format
We started using our own timestamp_t type and PRItime format
specifier to go along with it, so that we can later change the
underlying type and output format more easily, but this does not
play well with gettext tools.
Because gettext tools need to keep the *.po file portable across
platforms, they have to special-case the format specifiers like
PRIuMAX that are known types in inttypes.h, instead of letting CPP
handle strings like
"%" PRIuMAX " seconds ago"
as an ordinary string concatenation. They fundamentally cannot do
the same for our own custom type/format.
Given that po/git.pot needs to be generated only once every release
and by only one person, i.e. the l10n coordinator, let's update the
Makefile rule to generate po/git.pot so that gettext tools are run
on a munged set of sources in which all mentions of PRItime are
replaced with PRIuMAX, which is what we happen to use right now.
This way, developers do not have to care that PRItime does not play
well with gettext, and translators do not have to care that we use
our own PRItime.
The credit for the idea to munge the source files goes to Dscho.
Possible bugs are mine.

doc: reformat the paragraph containing the 'cut-line'
The paragraph that describes the 'scissors' cleanup mode of
'commit' had the 'cut-line' in the middle of a sentence. This
made it possible for the line to get wrapped on smaler windows.
This shouldn't be the case as it makes it hard for the user to
understand the structure of the cut-line.
Reformat the pragraph to make the 'cut-line' stand on a line of
it's own thus distinguishing it from the rest of the paragraph.
