I think the use of "-path" here is more complicated then it needs to be,
especially if you more than one sub-repo. This will work instead:
find . \! -path '*_darcs*' -prune -o -print0 | xargs -0 grep string
I also wasn't clear what '/dev/null' did, so I removed it. :)

These "NUL" options have reached FreeBSD at least, which means they've
reach Mac OS X, too.
