I think the uniquification shouldn't be done in the completion table.

All the fancy rewriting to make things shorter should be done in the
completion-style, instead.  The style code can choose to return different
kinds of results for completion-all-completions (which gets displayed
in *Completions*, in Company, or in Icomplete-mode and where we should
try and reduce redundancy) and for completion-try-completion.

So completion-all-completions can return names like "foo<bar>" while
completion-try-completion can return "~/src/file/foo/toto/bar.agda".

Another option is to use a completely different completion code
(e.g. that's what filecache.el does).

I generally don't like the idea that the same text would fail to behave
in the same way when written by hand by the user (in which case it
won't have that text-property).
