Subject: [PATCH] Pickaxe fixes.
X-Git-Tag: v0.99~422
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=e25de75696dc99f327c8dd8e2cba937939e281ca;p=git.git

[PATCH] Pickaxe fixes.

A bug in the command line argument parsing code was making
pickaxe not to work at all in diff-cache and diff-files commands.
Embarrassingly enough, the working pickaxe in diff-tree tells me
that it was not working in these two commands from day one.
This patch fixes it.

Also updates the documentation to describe the --pickaxe-all option.
