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.
