[PATCH v3 00/15] Mark "init", "clone", and "add" output for translation

Hi again,

To make the primitives introduced by v2 more concrete, here's a series including a few gettextization patches. I don't plan to send more of these unless there is some agreement that the basic structure is right. Maybe by next time I'll hunker down and write myself a tool to check that a commit only inserts "_("-")" pairs (maybe using diff --word-diff?)

This series still includes the skeleton gettext.h wrapper.

Changes from v1:

 - clearer commit messages, hopefully
 - clearer documentation for GETTEXT_POISON in the makefile

Please feel free to try it out, complain, ack, send patches, and so on.

Jonathan Nieder (2):
  i18n: do not poison translations unless GIT_GETTEXT_POISON envvar is
    set
  update-index --refresh --porcelain: add missing const

Ævar Arnfjörð Bjarmason (13):
  i18n: add no-op _() and N_() wrappers
  tests: add GETTEXT_POISON to simulate unfriendly translator
  Makefile: "pot" target to extract messages marked for translation
  init: mark basic messages for translation
  init: mark "Initialized [...] repository" for translation
  clone: mark basic messages for translation
  clone: split "Cloning into" message into two
  clone: mark "Cloning into" message for translation
  add: mark basic messages for translation
  add: mark "The following paths are ignored" for translation
  add: mark "did not match any files" for translation
  add -u --verbose: mark "remove '%s'" for translation
  add --refresh --verbose: mark "Unstaged changes" heading for
    translation
