[PATCH v3 0/4] git-gui blame: use textconv

["Clément Poulain" <clement.poulain@ensimag.imag.fr>]

This patch adds support of textconv to git-gui blame.

It is based on our previous work which adds textconv support to blame:
http://mid.gmane.org/1275921713-3277-1-git-send-email-axel.bonnet@ensimag.imag.fr
It also uses a git-gui patch done by Clemens Buchacher which adds textconv
support to git-gui diff: http://mid.gmane.org/20100415193944.GA5848@localhost.

git-gui blame is based on cat-file to get the content of the file in different
revisions, so the patch adds textconv support to cat-file.
The first part of this patch adds get_sha1_with_context() in order to know 
the pathname of the concerned blob, as textconv needs it to work.

This third version corrects one bug and some compilation warnings

Clément Poulain (4):
  sha1_name: add get_sha1_with_context()
  textconv: support for cat_file
  git gui: use textconv filter for diff and blame
  t/t8007: test textconv support for cat-file
