The hook would be interface specific because it is the interface which
has modified the case of the completion.

My reasons for not using :exit-function would be:
- If the completion was inserted using a different interface then the
function would be running unnecessarily.
- For completion functions that I didn't write, :exit-function isn't
going to be set with the expectation that a particular completion
interface and case preference is used to insert the candidate.
That said, I am just trying to think of an easy mechanism to preserve
the case of the candidate. A hook may generally be useful, but adding a
hook does not solve the underlying problem that I am describing here.
Perhaps it is best to just pause for the moment while you get additional
feedback from other users.
Thanks,
Morgan
