Was trying to edit an artist in http://test.musicbrainz.org/release/f3502c46-7762-47ae-be1d-d6da82e6fdac/ to try a trac bug, and I discovered that even if I tried to put the same artist in, RE would think it was a collab. It is nice that it looks for collabs, but if I enter Mitx I want it to be Mitx, not "Mit & x" or "M, i, t & x", and certainly not for it to ask me to enter the missing artists "Mit" and "x". Also, it appears as "Mit & x" for a while in the tracklist, but later it turns to "Mitx". If it's going to decide it is "Mit & x", I'd like it not to hide it from me.
