And use UINT_MAX as the default value.  The consequence of this is that there's no truely "unlimited" matching mode any more, but I think with a limit of UINT_MAX this probably isn't a problem.

In practice, unsigned int is probably large enough too, but there's no such guarantee.

Converted to size_t in latest version.
