I think I'd be more interested in an 'hg qpop --no-changes' which would pop a patch without updating the files in the working copy, since if we had that you could just use qrecord for patch splitting needs and other types of trickery.

Both is probably even better, but mq is already a nightmare of extra commands as it is...
