This is a bad example, because the leading '//' cannot be removed without
potentially changing the file's location.  It's in POSIX that exactly 2
slashes should not be reduced to '1' if it is at the beginning of the path.

The ones in the middle -- yes, but even if they were fixed, the two
in front might not match a single -- because some OS's use

Can your exclude use a regular expression?, can you say:
in the exclude patterns? (assuming a POSIX RE (not a file wildcard)).
