[PATCH 0/4] i18n: Add shell script translation infrastructure

As threatened this is the updated shell script translation infrastructure that I'm submitting now that 1.7.5 has been out for a bit.

This adds skeleton no-op functions to git-sh-i18n.sh analogous to the gettext.c skeleton functions for C, adds *.sh scripts to the "pot" target for message extraction, and updates the git-sh-i18n--envsubst tests to use the new test_i18ncmp function.

Ævar Arnfjörð Bjarmason (4):
  git-sh-i18n--envsubst: our own envsubst(1) for eval_gettext()
  git-sh-i18n.sh: add no-op gettext() and eval_gettext() wrappers
  git-sh-i18n.sh: add GIT_GETTEXT_POISON support
  Makefile: add xgettext target for *.sh files
