[PATCH/RFC 0/2] git diff --UTF-8

[tboegi@web.de]

From: Torsten Bögershausen <tboegi@web.de>

RFC patch: convert files from e.g. UTF-16 into UTF-8 while running
"git diff".
The diff must be called with "git diff --UTF-8" and the "encoding"
attribute must be set for the file(s).

The commit messages may need some improvements, and a closer look
at diff.c, how command line options are forwared, is appreciated.

It may even be possible to integrate t4066 somewhere...

Torsten Bögershausen (2):
  convert_to_git(): checksafe becomes an integer
  git diff: Allow to reencode into UTF-8
