What's the use case of using -m together with --with-tree to begin with?
I think the only sensible other option that makes sense with --with-tree
is --error-unmatch.

The reason I ask this question is that the cleanest fix to the issue might
turn out to be to forbid that combination of the options, if it turns out
that it does not make any sense.
