What would folks think about changing

to permit multiple wildcards, but to restrict the number of matches
returned (configurable with a directive, of course)?
Over a small pattern space, uploads/*/* is often very useful.
What would be the sane default? 1,000 entries?
For anonftp usage I would prefer the restrictive behaviour, it's good
enough for most users and most decent ftpd's already does it that way.
For example, you can find this in ls.c in vsftpd:
--8--
* Note that pattern matching is only supported within the last path
* component. For example, searching for /a/b/? will work, but searching
* for /a/?/c will not.
--8--
which is a sane behaviour for a public server in my world.
For non-anonftp usage limiting the number of matches might be OK, if
the thing stops recursion when hitting the limit and not just limit
the reply send to the client ;)
So my vote would be default to restrictive, a more relaxed behaviour
must be explicitly configured.
