If CDPATH is set, "cd" prints its destination to stdout, causing
the common (cd a && tar cf - .) | (cd b && tar xf -) idiom to fail.
For example:

 make -C templates DESTDIR='' install
 make[1]: Entering directory `/users/e477610/exptool/src/git-1.7.0.2/templates'
 install -d -m 755 '/home/e477610/exptool/share/git-core/templates'
 (cd blt && gtar cf - .) | \
	(cd '/home/e477610/exptool/share/git-core/templates' && umask 022 && gtar xof -)
 gtar: This does not look like a tar archive

Most git scripts already protect against use of CDPATH through
git-sh-setup, but the Makefile doesn’t.

If a revision is specified, it happens not to have any commits, don't
use the default revision.  By doing so, surprising and undesired
behavior can happen, such as showing the reflog for HEAD when a branch
was specified.

As Vladimir reported, "git log -g refs/stash" surprisingly showed the reflog
of HEAD if the message in the reflog file was too long.  To fix this, convert
for_each_recent_reflog_ent() to use strbuf_getwholeline() instead of fgets(),
for safety and to avoid any size limits for reflog entries.

Also reverse the logic of the part of the function that only looks at file
tails.  It used to close the file if fgets() succeeded.  The following
fgets() call in the while loop was likely to fail in this case, too, so
passing an offset to for_each_recent_reflog_ent() never worked.  Change it to
error out if strbuf_getwholeline() fails instead.

Consistently using test_cmp would make debugging test scripts far easier,
as output from them run under "-v" option becomes readable.

Besides, some platforms' "diff" implementations lack "-q" option.

These tests have been broken since they were introduced in commits
ca2cedba (git-submodule: add support for --rebase., 2009-04-24) and
42b49178 (git-submodule: add support for --merge., 2009-06-03).
'git submodule init' expects the submodules to exist in the index.
In this case, the submodules don't exist and therefore looking for
the submodules will always fail. To make matters worse, git submodule
fails visibly to the user by saying:

error: pathspec 'rebasing' did not match any file(s) known to git.
Did you forget to 'git add'?

but doesn't return an error code. This allows the test to fail silently.
Fix it by adding the submodules first.
