The interface to custom low-level merge driver was modeled to be
capable of driving programs like "merge" (from the RCS suite) that
can produce result solely by looking at three files that hold
contents of common ancestor, ours and theirs. The information we
feed to the external drivers via the command line placeholders %O,
%A, and %B were designed to be purely about contents by giving
names of the temporary files that hold these variants without
exposing the original pathname. No matter where the result goes,
merging the same three variants should produce the same result,
contents is the king, that is the Git way.
The external driver interface, however, is meant to help people to
step outside the Git worldview, and sometimes people want to know
the final path that the resulting merged contents would be stored
in. Expose this to the external drivers via a new placeholder %P.

While parsing the command-line arguments, git-pull stops parsing at the
first unrecognized option, assuming that any subsequent options are for
git-fetch, and can thus be kept in the shell's positional parameters
list, so that it can be passed to git-fetch via the expansion of "$@".
However, certain functions in git-pull assume that the positional
parameters do not contain any options:
* error_on_no_merge_candidates() uses the number of positional
parameters to determine which error message to print out, and will
thus print the wrong message if git-fetch's options are passed in as
well.
* the call to get_remote_merge_branch() assumes that the positional
parameters only contains the optional repo and refspecs, and will
thus silently fail if git-fetch's options are passed in as well.
* --dry-run is a valid git-fetch option, but if provided after any
git-fetch options, it is not recognized by git-pull and thus git-pull
will continue to run the merge or rebase.
Fix these bugs by teaching git-pull to parse git-fetch's options as
well. Add tests to prevent regressions.
This removes the limitation where git-fetch's options have to come after
git-merge's and git-rebase's options on the command line. Update the
documentation to reflect this.

"git format-patch --ignore-if-in-upstream A..B", when either A or B
is a tag, failed miserably.
This is because the code passes the tips it used for traversal to
clear_commit_marks(), after running a temporary revision traversal
to enumerate the commits on both branches to find if they have
commits that make equivalent changes. The revision traversal
machinery knows how to enumerate commits reachable starting from a
tag, but clear_commit_marks() wants to take nothing but a commit.
In the longer term, it might be a more correct fix to teach
clear_commit_marks() to do the same "committish to commit"
dereferencing that is done in the revision traversal machinery,
but for now this fix should suffice.

A hunk like this in a hand-edited patch without correctly adjusting

it as a corrupt patch. We just read two context lines and discard
the remainder as cruft, which we must do in order to ignore the
e-mail footer. Notice that the patch does not change anything and
signal an error.
Note that this fix will not help if the hand-edited hunk header were
"@@ -660,3, +660,2" to include the removal. We would just remove
the old text without adding the new one, and treat "+ some new text"
and everything after that line as trailing cruft. So it is dubious
that this patch alone would help very much in practice, but it may

We set revs->ignore_missing_links to instruct the
revision-walking machinery that we know the history graph
may be incomplete. For example, we use it when walking
unreachable but recent objects; we want to add what we can,
but it's OK if the history is incomplete.
However, we still print error messages for the missing
objects, which can be confusing. This is not an error, but
just a normal situation when transitioning from a repository
last pruned by an older git (which can leave broken segments
of history) to a more recent one (where we try to preserve
whole reachable segments).

If both core.bare and core.worktree are set, we complain
about the bogus config and die. Dying is good, because it
avoids commands running and doing damage in a potentially
incorrect setup. But dying _there_ is bad, because it means
that commands which do not even care about the work tree
cannot run. This can make repairing the situation harder:
[setup]
$ git config core.bare true
$ git config core.worktree /some/path
[OK, expected.]
$ git status
fatal: core.bare and core.worktree do not make sense
[Hrm...]
$ git config --unset core.worktree
fatal: core.bare and core.worktree do not make sense
[Nope...]
$ git config --edit
fatal: core.bare and core.worktree do not make sense
[Gaaah.]
$ git help config
fatal: core.bare and core.worktree do not make sense
Instead, let's issue a warning about the bogus config when
we notice it (i.e., for all commands), but only die when the
command tries to use the work tree (by calling setup_work_tree).
So we now get:
$ git status
warning: core.bare and core.worktree do not make sense
fatal: unable to set up work tree using invalid config
$ git config --unset core.worktree
warning: core.bare and core.worktree do not make sense
We have to update t1510 to accomodate this; it uses
symbolic-ref to check whether the configuration works or
not, but of course that command does not use the working
tree. Instead, we switch it to use `git status`, as it
requires a work-tree, does not need any special setup, and
is read-only (so a failure will not adversely affect further
tests).
In addition, we add a new test that checks the desired
behavior (i.e., that running "git config" with the bogus
config does in fact work).
