Sorry about the wait. I've pushed the patch now in commit a691e811e2, to 
get it in time for the next release.

Regarding a guideline, not sure if we had one (though it sounds good), 
but I think the only times where it would matter, is when a directory 
name is repeated multiple times (e.g. Compilation buffer).

And in places line a header line where it's only printed once, it 
doesn't matter as much, but can can show the expanded version, to make 
it doubly clear.
