I'm not about non-interactive searches, seldom use them - can something
like `dired-isearch-filenames-regexp' be done non-interactively?

Anyway, my complete idea was: whenever we provide a special search
command that limits isearch to certain entities, like file names in a
dired buffer, we always guarantee that point can be matched at the
beginning of each entity with \= (and maybe also \` and ^).  In an
interactive search \= is quite useless (right?), so we can use it for
that and avoid hacks that would probably be worse.

We would still not have a solution to match the end of the entities,
however.  Fortunately for files in dired $ works (by coincidence).

Why not.

Michael.
