wishlist: diffstat could understand the output of colordiff

[Jay Foad]

I think it would be nice if diffstat understood the output of colordiff. Currently I get:

$ colordiff /etc/group /etc/passwd | diffstat
 0 files changed

Presumably this is just a matter of diffstat ignoring some control codes.

(Background: I have configured my svn to use colordiff for diffs, so I can do e.g. "svn diff | less" to see a nice colored diff in my terminal. Unfortunately this means that the simple "svn diff | diffstat" no longer works. Yes I could work around this with something like "svn diff --diff-cmd diff | diffstat", but it would be nice if it Just Worked.)
