So a "list of strings or cons cells, an obarray, a hash table, or a completion function". When you know what to look for, you'll find it (in the info docs for try-completion). >> 2.

Yes, I could. I just thought that there's probably some kind of metadata I could attach for customizing the display. So I guess the best thing to do is to format the entries as you suggest and put a text property on the text holding the absolute path so that I don't have to reconstruct it myself which could be error-prone if the directory or basename contain parens themselves.
