[RFC/PATCH 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 the work already done here: http://mid.gmane.org/1275562038-7468-1-git-send-email-axel.bonnet@ensimag.imag.fr, and uses a git-gui patch done by Clemens Buchacher (http://mid.gmane.org/20100415193944.GA5848@localhost) which adds textconv support to git-gui diff.

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.

After a discussion with Jeff King and Matthieu Moy, it appears that creating a context cache is a good way to know the pathname of the concerned blob, as textconv needs a pathname to work. The first part of the patch adds this cache
