Here's the patch. The first part refactors em-glob.el a bit, and 
converts globs into regexps ahead of time. This is partly to make the 
second patch simpler, but also improves performance by a few percent 
when `eshell-glob-entries' examines many directories: it no longer 
repeatedly converts the same glob component for each sibling directory.

The second part is the actual patch for this bug.
