I looked at this.  It turns out not to matter -- svn puts ".text-base"
at the end of the copies it stores in .svn, so mkid is already
ignoring them by default.

I'm hoping the traversal costs are not severe :-)

Re-using the prune feature for this looked like a pain.  From what I
can tell, -p assumes the argument is a file name in the current
directory, not a base file name to be ignored everywhere it is seen.
Also, 'mkid -p .svn' prints an error if there is not in fact a .svn
directory.

Hard-coding the various names into the search loop may be easy (I
didn't look).  But it seems a bit ugly.  Also perhaps you'd want a way
to disable the internal pruning...?  At that point the patch starts
looking a bigger.

I assume this one must be hard or someone would have done it already :-)
