Oh, it's bad.

The yucky part is the thought that we'd need to recursively crawl the whole
copy target to find mergeinfo to duplicate.

I dunno the mergeinfo schema, but it'd be nice if we had an API to select
all the mergeinfo for paths in and under /foo, and then duplicate those as
mergeinfo for paths in and under /bar (svn_fs_mergeinfo__deep_copy?).

But what about some variations on this? What happens if you copy /foo to
/bar (in your situation) and delete /bar/branches at the same time? Now
you're shortcutted deep copy will leave mergeinfo in the index for paths
that don't even exist any more.
