That's nice :)

I haven't been able to reproduce this with a recent crew build.  It may
be a false alarm, my apologies.  I remember that it used to do something
funny with mixed TAB and SPC characters and I disabled it in my ~/.hgrc
back in March 2009:

% keramida at kobe:/home/keramida$ hg log -v -r d94746159432

% description:
% hg: disable the color extension
% The color extension does something strange with whitespace in the
% patchfile before displaying it.  I like seeing TAB vs. SPC changes,
% instead of hiding them, so disable the extension until I find out
% how to fix it.

But it looks much better now.  I think I'll try using it for a few weeks
and see if I can reproduce this again.  If not, then so much the better,
as I like the colorized output a lot :-)
