Ah.  Looks like I tweaked the comma usage and sentence structure a
little.  Sorry, force of habit --- I shouldn't have.

If we're going to keep the changes together, here's how I would phrase
the commit message:

	Mark messages in git-rebase.sh for translation.  While doing this
	it was 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.

I haven't tested or reviewed this patch in detail, so even though it
looks good, I'd prefer it not to have my Reviewed-by.  (See
Documentation/SubmittingPatches: '"Reviewed-by:", unlike the other
extra tags, can only be offered by the reviewer'.)  If you'd like to
credit my help, something like "With advice from Jonathan." would be
fine.

Could we add a comment so others do not have to wonder what
human-readable message prompts the test_i18ngrep here?  e.g

	# "Does not point to a valid commit: invalid-ref"
	#
	# NEEDSWORK: This "grep" is fine in real non-C locales, but
	# GETTEXT_POISON poisons the refname along with the enclosing
	# error message.
	test_i18ngrep invalid-ref err

In the long run we may be able to turn this back to a "grep" again,
since any reasonable translation will keep the $onto_name somewhere
in the message.  But changing it to test_i18ngrep for now is the
right thing to do, until something like Duy's more sophisticated
version of GETTEXT_POISON arrives. (<-- [*])
