The problem is that this check has to be made at each file access.
Depending on file access patterns on Darcs this could range from
not-so-heavy to unbearable.

Anyway, there are more than one people asking for it, so maybe
implementing it could be nice. If it's too slow for some usage
patterns, we can use an option to disable the checks.
