As you can see from this transcript, ^[[00m nonsense is injected into
the rollback text.  Colouring should be suppressed in the default long
description when using rollback --edit.

    $ darcs init
    $ touch x
    $ darcs rec -lam x x
    Recording changes in "x":

Hi Nicolas,

I don't really know what's going on here.  Could you comment?  Is this just the
wrong printer being used somewhere?

Thanks!

The following patch updated the status of issue1339 to be resolved:

* resolved issue1339: No longer use the color printer for the rollback log
