u"""Return selection function based on glob_str
The basic idea is to turn glob_str into a regular expression,
and just use the normal regular expression. There is a
complication because the selection function should return '2'
(scan) for directories which may contain a file which matches
the glob_str. So we break up the glob string into parts, and
any file which matches an initial sequence of glob parts gets
scanned.
Thanks to Donovan Baarda who provided some code which did some
things similar to this.
