Comment 1 for bug 36880

Point 2 is a duplicate of bug 33145.

We used to match on unambiguous names. We no longer do this because, unfortunately, it is hard to decide on whether an unambiguous match is correct or not -- if I enter "mbp" and your account name is "mpool" but there's a guy called "rombpot", the wrong thing happens. To do this properly we'd need to always confirm unless we got an exact match.

There is the issue of the error message still; I'm not sure if that's a dupe of bug 36878 or not.
