I actually kinda like this idea. It was already a concern of some that if
you made a branch but didn't merge to it, it never showed any hints about
places you might want to merge from. Maybe this is a chance to resolve
that, too, but simply calling the suggest_merge_sources() API (which returns
a superset of the mergeinfo paths) and displaying those paths as options.
Given that, a script could iterate over the output of 'svn mergeinfo
--show-revs=sources' and call 'svn mergeinfo --show-revs=eligible
--from-source=SOURCE' and so on.
