Subject: [PATCH] git-apply: Don't barf when --stat'ing a diff with no line changes.
X-Git-Tag: v0.99~224
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=69f956e10484f92f9e0ab191b668c79d697b9f0f;p=git.git

[PATCH] git-apply: Don't barf when --stat'ing a diff with no line changes.

Diffs with only mode changes didn't pass through git-apply --stat.

[ Linus' note: they did for me, on my ppc64, where division by zero just
  silently returns zero.  Duh.  ]
