Bug: "LF will be replaced by CRLF" warning duplicated two (or three) times

[Eric Raible]

A single "LF will be replaced by CRLF" message is expected in certain cases.
But two warnings per file are produced with git-diff --patch-with-stat.
Posted here rather than to the msysgit list b.c. I'm guessing it's not
msysgit-specific.

It's even possible to trigger three identical warnings:
$ git add -p
warning: LF will be replaced by CRLF in file42
warning: LF will be replaced by CRLF in file42
warning: LF will be replaced by CRLF in file42
diff --git a/file42 b/file42

This is obviously not a show-stopper, but I thought it worth reporting anyway.
