The pagination functionality in git am has some problems:
- It does not check if stdout is a tty, so it always paginates.
- If $GIT_PAGER uses any environment variables, they are being
ignored, since it does not run $GIT_PAGER through eval.
- If $GIT_PAGER is set to the empty string, instead of passing
output through to stdout, it tries to run $dotest/patch.
Fix them. While at it, move the definition of git_pager() to
git-sh-setup so authors of other commands are not tempted to
reimplement it with the same mistakes.

gitweb: Die if there are parsing errors in config file
Otherwise the errors can propagate, and show in damnest places, and
you would spend your time chasing ghosts instead of debugging real
problem (yes, it is from personal experience).
This follows (parts of) advice in `perldoc -f do` documentation.
This required restructoring code a bit, so we die only if we are reading
(executing) config file. As a side effect $GITWEB_CONFIG_SYSTEM is always
available, even when we use $GITWEB_CONFIG.

In commit dec543e (am -i, git-svn: use "git var GIT_PAGER"), I tried
to teach git svn to defer to git var on what pager to use. In the
process, I introduced two bugs:
- The value set for $pager in config_pager has local scope, so
run_pager never sees it;
- git var cannot tell whether git svn’s output is going to a
terminal, so the value chosen for $pager does not reflect that
information.
Fix them.

git.1: Clarify the behavior of the --paginate option
The --paginate option is meant to negate the effect of an explicit or

Make 'git var GIT_PAGER' always print the configured pager
Scripted commands that want to use git’s configured pager know better
than ‘git var’ does whether stdout is going to be a tty at the
appropriate time. Checking isatty(1) as git_pager() does now won’t
cut it, since the output of git var itself is almost never a terminal.
The symptom is that when used by humans, ‘git var GIT_PAGER’ behaves
as it should, but when used by scripts, it always returns ‘cat’!
So avoid tricks with isatty() and just always print the configured
pager.
This does not fix the callers to check isatty(1) themselves yet.
Nevertheless, this patch alone is enough to fix 'am --interactive'.
Thanks to Sebastian Celis for the report and Jeff King for the
analysis.

builtin-notes: Add "copy" subcommand for copying notes between objects
This is useful for keeping notes to objects that are being rewritten by e.g.
'git commit --amend', 'git rebase', or 'git cherry-pick'.
"git notes copy <from> <to>" is in practice equivalent to
"git notes add -C $(git notes list <from>) <to>", although it is somewhat
more convenient for regular users.
"git notes copy" takes the same -f option as "git add", to overwrite existing
notes at the target (instead of aborting with an error message).
If the <from>-object has no notes, "git notes copy" will abort with an error
message.

git notes add [-f] -C $(git notes list A) B
To move instead of copying, you simply remove the notes from the source

Notes API: prune_notes(): Prune notes that belong to non-existing objects
When an object is made unreachable by Git, any notes that annotate that object
are not automagically made unreachable, since all notes are always trivially
reachable from a notes ref. In order to remove notes for non-existing objects,
we therefore need to add functionality for traversing the notes tree and
explicitly removing references to notes that annotate non-reachable objects.
Thus the notes objects themselves also become unreachable, and are removed
by a later garbage collect.
prune_notes() performs this traversal (by using for_each_note() internally),
and removes the notes in question from the notes tree.
Note that the effect of prune_notes() is not persistent unless a subsequent
call to write_notes_tree() is made.

Teach notes code to properly preserve non-notes in the notes tree
The note tree structure allows for non-note entries to coexist with note
entries in a notes tree. Although we certainly expect there to be very
few non-notes in a notes tree, we should still support them to a certain
degree.
This patch teaches the notes code to preserve non-notes when updating the
notes tree with write_notes_tree(). Non-notes are not affected by fanout
restructuring.
For non-notes to be handled correctly, we can no longer allow subtree
entries that do not match the fanout structure produced by the notes code
itself. This means that fanouts like 4/36, 6/34, 8/32, 4/4/32, etc. are
no longer recognized as note subtrees; only 2-based fanouts are allowed
(2/38, 2/2/36, 2/2/2/34, etc.). Since the notes code has never at any point
_produced_ non-2-based fanouts, it is highly unlikely that this change will
cause problems for anyone.
The patch also adds some tests verifying the correct handling of non-notes
in a notes tree.

be easily used from other builtins to manipulate the notes tree.

Refactor notes concatenation into a flexible interface for combining notes
When adding a note to an object that already has an existing note, the
current solution is to concatenate the contents of the two notes. However,
the caller may instead wish to _overwrite_ the existing note with the new
note, or maybe even _ignore_ the new note, and keep the existing one. There
might also be other ways of combining notes that are only known to the
caller.
Therefore, instead of unconditionally concatenating notes, we let the caller
specify how to combine notes, by passing in a pointer to a function for
combining notes. The caller may choose to implement its own function for
notes combining, but normally one of the following three conveniently
supplied notes combination functions will be sufficient:
- combine_notes_concatenate() combines the two notes by appending the
contents of the new note to the contents of the existing note.
- combine_notes_overwrite() replaces the existing note with the new note.
- combine_notes_ignore() keeps the existing note, and ignores the new note.
A combine_notes function can be passed to init_notes() to choose a default
combine_notes function for that notes tree. If NULL is given, the notes tree
falls back to combine_notes_concatenate() as the ultimate default.
A combine_notes function can also be passed directly to add_note(), to
control the notes combining behaviour for a note addition in particular.
If NULL is passed, the combine_notes function registered for the given
notes tree is used.

initialized to an empty state. This will become useful in the future when
manipulating the notes tree through the notes API.

git log -p -m: document -m and honor --first-parent
git log -p -m is used to show one merge entry per parent, with an
appropriate diff; this can be useful when examining histories where
full set of changes introduced by a merged branch is interesting, not
only the conflicts.
This patch properly documents the -m switch, which has so far been
mentioned only as a fairly special diff-tree flag.
It also makes the code show full patch entry only for the first parent
when --first-parent is used. Thus:
git log -p -m --first-parent
will show the history from the "main branch perspective", while also
including full diff of changes introduced by other merged in branches.
