[Pdx-pm] diff_painter.pl

[Matthew Wickline]

Speaking of "worst useful hack", I was recently convinced to put this
up on github.
    https://github.com/wickline/diff_painter/blob/master/diff_painter.pl

Pipe diffs to diff_painter.pl and they look prettier.
...diff_painter.pl itself is very un-pretty.

unpainted:
    http://wickline.org/diff_painter/exhibit_A.png
    uh... some stuff changed

typical diff colorizer:
    http://wickline.org/diff_painter/exhibit_B.png
    uh... some stuff changed and now it's in color

piped to diff_painter.pl:
    http://wickline.org/diff_painter/exhibit_C.png
    holy painless code reviews, batman!

diffs are optimized for patch. Painted diffs are optimized for humans.
Sometimes it messes up. Then you get "christmas barf".

Your coworkers will thank you if you share it with them. Also, share
ack if you haven't yet.
