git-svn: Protect against "diff.color = true".

[Junio C Hamano <gitster@pobox.com>]

If the configuration of the user has "diff.color = true", the
output from "log" we invoke internally added color codes, which
broke the parser.

  Here is my attempt -- I do not have an easy access to SVN repo
  to interoperate with, so a testing by real-world users and an
  Ack is appreciated.  I think some fix for this issue (not
  necessarily this patch) should be in 1.5.3 final.
