[PATCH v2 0/4] i18n: Add shell script translation infrastructure

This is v2 of the "Add shell script translation infrastructure" series. Changes:

  * The Author & Documentation sections from the documentation are now
    gone. These should no longer be included, but the patch series
    preceded that convention.

  * Update the git-sh-i18n.txt and git-sh-i18n--envsubst.txt
    documentation to accurately reflect what the skeleton fall-through
    wrappers do.

  * Updated the commit message for "git-sh-i18n--envsubst: our own
    envsubst(1) for eval_gettext()" to not include a lengthy
    description of failed eval_gettext experiments at Junio's
    suggestion.

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
