Then it should not be hard to extend the existing code to
do "fuzzy" comparisons using generic case- and accent folding.

Because I think that strict glob-like patterns need to be supported
as well, I suggest to have two options:

    --search does a fuzzy search just like we use it in other commands.
             We implicitly add leading an trailing '*'.

    --search-glob performs a fully case- and accent-sensitive glob

As with '--search' alone, the user is free to specify any number
and combination of the above but without the support of '--search-and' -
at least for now.

Thoughts? Better names for '--search-glob'?
