I don't like that. Normally "color" is shut down for non tty output.
But this increase the risk that export creates a non usable export patch if 
this detection fails for some reasons.
We have "hg log -pvr" that does the job for coloring output, and "hg export" 
should be just for exports. I don't see the point of risking to break scripts 
when we already have a solution.

May be just a note in the help of export pointing to "hg log -pvr", though 
referring to an extension from the core does not seem a good idea as well.

Regards.
Gilles.
