darcs-all breakage

[Manuel M T Chakravarty]

Unfortunately, a change to darcs-all snug inadvertently into the 
type families patch that breaks it for ssh repos at least with Perl 
5.8.8 (on MacOS).  A patch that reverts the change is in the repo 
now.  So, if you experience problems just do a plain "darcs pull" 
first, then darcs-all should be fine again.

Maybe validate should test darcs-all, too...well, not seriously.

Mea culpa,
Manuel
