push: start warning upcoming default change for push.default

In preparation for flipping the default to the "simple" mode from
the "matching" mode that is the historical default, start warning
users when they rely on unconfigured "git push" to default to the
"matching" mode.

Also, advertise for 'simple' where 'current' and 'upstream' are advised.

difftool: Eliminate global variables

Organize the script so that it has a single main() function which
calls out to dir_diff() and file_diff() functions. This eliminates
"dir-diff"-specific variables that do not need to be calculated when
performing a regular file-diff.

difftool: Use symlinks when diffing against the worktree

Teach difftool's --dir-diff mode to use symlinks to represent
files from the working copy, and make it the default behavior
for the non-Windows platforms.

Using symlinks is simpler and safer since we do not need to
worry about copying files back into the worktree.
The old behavior is still available as --no-symlinks.

difftool: Handle finding mergetools/ in a path with spaces

Use the original File::Find implementation from bf73fc2 (difftool:
print list of valid tools with '--tool-help', 2012-03-29) so that we
properly handle mergetools/ being located in a path containing
spaces.

One small difference is that we avoid using a global variable by
passing a reference to the list of tools.

i18n: rebase: mark messages for translation

Mark messages in git-rebase.sh for translation.  While doing this
Jonathan noticed that the comma usage and sentence structure of the
resolvemsg was not quite right, so correct that and its cousins in
git-am.sh and t/t0201-gettext-fallbacks.sh at the same time.

Some tests would start to fail with GETTEXT_POISON turned on after
this update.  Use test_i18ncmp and test_i18ngrep where appropriate
to mark strings that should only be checked in the C locale output
to avoid such issues.

help.c::uniq: plug a leak

We observe that the j-1 element can serve the same purpose as the i-1
element that we use in the strcmp(); it is either:

  1. Exactly i-1, when the loop begins (and until we see a duplicate).

  2. The same pointer that was stored at i-1 (if it was not a duplicate,
     and we just copied it into place).

  3. A pointer to an equivalent string (i.e., we rejected i-1 _because_
     it was identical to j-1).

git-submodule: work with GIT_DIR/GIT_WORK_TREE

The combination of GIT_DIR and GIT_WORK_TREE can be used to manage
files in one directory hierarchy while keeping the repository that
keeps track of them outside the directory hierarchy.  For example:

    git init --bare /path/to/there
    alias dotfiles="GIT_DIR=/path/to/there GIT_WORK_TREE=/path/to/here git"

    cd /path/to/here
    dotfiles add file
    dotfiles commit -a -m "add /path/to/here/file"
    ...

lets you manage files under /path/to/here/ in the repository located
at /path/to/there.

git-submodule however fails to add submodules, as it is confused by
GIT_DIR and GIT_WORK_TREE environment variables when it tries to
work in the submodule, like so:

    dotfiles submodule add http://path.to/submodule
    fatal: working tree '/path/to/here' already exists.

Simply unsetting the environment where the command works on the
submodule is sufficient to fix this, as it has set things up so
that GIT_DIR and GIT_WORK_TREE do not even have to point at the
repository and the working tree of the submodule.

checkout: don't confuse ref and object flags

When we are leaving a detached HEAD, we do a revision traversal to
check whether we are orphaning any commits, marking the commit we're
leaving as the start of the traversal, and all existing refs as
uninteresting.

Prior to commit 468224e5, we did so by calling for_each_ref, and
feeding each resulting refname to setup_revisions.  Commit 468224e5
refactored this to simply mark the pending objects, saving an extra
lookup.

However, it confused the "flags" parameter to the each_ref_fn
clalback, which is about the flags we found while looking up the ref
with the object flag.  Because REF_ISSYMREF ("this ref is a symbolic
ref, e.g. refs/remotes/origin/HEAD") happens to be the same bit
pattern as SEEN ("we have picked this object up from the pending
list and moved it to revs.commits list"), we incorrectly reported
that a commit previously at the detached HEAD will become
unreachable if the only ref that can reach the commit happens to be
pointed at by a symbolic ref.

t7502: clean up fake_editor tests

Using write_script saves us a few lines of code, and means
we consistently use $SHELL_PATH.

We can also drop the setting of the $pwd variable from
$(pwd). In the first instance, there is no reason to use it
(we can just use $(pwd) directly two lines later, since we
are interpolating the here-document). In the second
instance, it is totally pointless and probably just a
cut-and-paste from the first instance.

Finally, we can use a non-interpolating here document for
the final script, which saves some quoting.
