I took another stab at this, and got it to work; attached.
The version with advice is cleaner, but not by a whole lot.
The completion function calls a deuniquify function, and the top level
client code calls `try-completion' after calling `completing-read'. The
user sees an absolute filename in the completion buffer only if they
type <tab> twice on a unique file.
