Say you momentarily forget that boring needs to contain regexes, not globs, and your boring file contains just: *.whatever Then executing `darcs wh -l` gives: darcs failed: Text.Regex.Posix.String died: (ReturnCode 13,"Invalid preceding regular expression") Can we make this slightly more user-friendly? The error is fairly descriptive, but doesn't necessarily explain why and where it's come from.

N.B, you must be in a non-empty repo for the error to occur (touching a single file, in a clean repo is enough), as a guess, I'd say this is due to the regex only being used (and thus created) if there is a non-empty tree to be searched.

Yuck. Funny it hasn't been reported before. You're not the first one to find it.
