usability: don't ask questions if no reply is required
There has been a bug report by a corporate user that stated that
"spelling mistake of stash followed by a yes prints character 'y'
infinite times."
This analysis was false. When the spelling of a command contains
errors, the git program tries to help the user by providing candidates
which are close to the unexisting command. E.g Git prints the
following:
git: 'stahs' is not a git command. See 'git --help'.
Did you mean this?
stash
and then exits.
The problem with this hint is that it is not formally indicated as an
hint and the user is in fact encouraged to reply to the question,
whereas the Git command is already finished.
The user was unlucky enough that it was the command he was looking
for, and replied "yes" on the command line, effectively launching the
`yes` program.
The initial error is that the Git programs, when launched in
command-line mode (without interaction) must not ask questions,
because these questions would normally require a user input as a reply
that they won't handle indeed. That's a source of confusion on UX
level.
To improve the general usability of the Git suite, the following rule
was applied:
if the sentence
* appears in a non-interactive session
* is printed last before exit
* is a question addressing the user ("you")
the sentence is turned into affirmative and proposes the option.
The basic rewording of the question sentences has been extended to
other spots found in the source.

Fix the remaining tests that failed with core.autocrlf=true

reason that nobody thought to mark files as LF-only as needed.
The symptom is a test suite that fails left and right when being checked

Mostly, the problems stem from Git's (LF-only) output being compared to
hard-coded files that are checked out with line endings according to
core.autocrlf (which is of course incorrect). This includes the two test
files in t/diff-lib/, README and COPYING.

On Windows, the default line endings are denoted by a Carriage Return
byte followed by a Line Feed byte, while Linux and MacOSX use a single
Line Feed byte to denote a line ending.
To help with this situation, Git introduced several mechanisms over the
last decade, most prominently the `core.autocrlf` setting.
Sometimes, however, a single setting is incorrect, e.g. when certain
files in the source code are to be consumed by software that can handle
only LF line endings, while other files can use whatever is appropriate
for the current platform.
To allow for that, Git added the `eol` option to its .gitattributes
handling, expecting every user of Git to mark their source code
appropriately.
Bash assumes that line-endings of scripts are denoted by a single Line
Feed byte. Therefore, shell scripts in Git's source code are one example
where that `eol=lf` option is *required*.
When generating common-cmds.h, the Unix tools we use generally operate on
the assumption that input and output deliminate their lines using LF-only
line endings. Consequently, they would happily copy the CR byte verbatim
into the strings in common-cmds.h, which in turn makes the C preprocessor
barf (that interprets them as MacOS-style line endings). Therefore, we
have to mark the input files as LF-only: command-list.txt and
Documentation/git-*.txt.
Quite a bit belatedly, this patch brings Git's own source code in line
with those expectations by setting those attributes to allow for a
correct build even when core.autocrlf=true.
This patch can be validated even on Linux, by using this cadence:

Teach receive-pack, in the case that push options are provided for a

This sets in stone the requirement that send-pack redundantly send its

pack-objects: disable pack reuse for object-selection options
If certain options like --honor-pack-keep, --local, or
--incremental are used with pack-objects, then we need to
feed each potential object to want_object_in_pack() to see
if it should be filtered out. But when the bitmap
reuse_packfile optimization is in effect, we do not call
that function at all, and in fact skip adding the objects to
the to_pack list entirely. This means we have a bug: for
certain requests we will silently ignore those options and
include objects in that pack that should not be there.
The problem has been present since the inception of the
pack-reuse code in 6b8fda2db (pack-objects: use bitmaps when
packing objects, 2013-12-21), but it was unlikely to come up
in practice. These options are generally used for on-disk
packing, not transfer packs (which go to stdout), but we've
never allowed pack reuse for non-stdout packs (until 645c432d6, we did not even use bitmaps, which the reuse
optimization relies on; after that, we explicitly turned it
off when not packing to stdout).
We can fix this by just disabling the reuse_packfile
optimization when the options are in use. In theory we could
teach the pack-reuse code to satisfy these checks, but it's
not worth the complexity. The purpose of the optimization is
to keep the amount of per-object work we do to a minimum.
But these options inherently require us to search for other
copies of each object, drowning out any benefit of the
pack-reuse optimization. But note that the optimizations
from 56dfeb626 (pack-objects: compute local/ignore_pack_keep
early, 2016-07-29) happen before pack-reuse, meaning that
specifying "--honor-pack-keep" in a repository with no .keep
files can still follow the fast path.
There are tests in t5310 that check these options with
bitmaps and --stdout, but they didn't catch the bug, and
it's hard to adapt them to do so.
One problem is that they don't use --delta-base-offset;
without that option, we always disable the reuse
optimization entirely. It would be fine to add it in (it
actually makes the test more realistic), but that still
isn't quite enough.
The other problem is that the reuse code is very picky; it
only kicks in when it can reuse most of a pack, starting
from the first byte. So we'd have to start from a fully
repacked and bitmapped state to trigger it. But the tests
for these options use a much more subtle state; they want to
be sure that the want_object_in_pack() code is allowing some
objects but not others. Doing a full repack runs counter to
that.
So this patch adds new tests at the end of the script which
create the fully-packed state and make sure that each option
is not fooled by reusable pack.

actually matter what we use for "plain text" attributes, as we never need
to output any text to any console in that case.
However, after working on stdout and stderr, is_console() is called with
stdin, and it still tries to initialize the "plain text" attributes if
they had not been initialized earlier. In this case, we cannot detect any
attributes, and we used an uninitialized value for them.
Naturally, Coverity complained about this use case because it could not
reason about the code deeply enough to figure out that we do not even use
those attributes in that case.
Let's just initialize the value to 0 in that case, both to avoid future
Coverity reports, and to help catch future regressions in case anybody
changes the order of the is_console() calls (which would make the text
black on black).

Replace a couple of broken links to gmane with links to other

With this change there's still 4 references left in the code:
