devel/ hangs in globbing

[Raphaël Droz]

Using the devel/ branch, with default options (simple ./configure), I
found that *sourcing* such a script would cause bash to hang using 100%
CPU. This does not happen using 4.2_p39.

> #!/bin/bash
> shopt -s extglob
> glob='@(|))'
> for i in /tmp/!($glob); do echo $i; done

[ bash-completion initialisation uses this kind of construct ]
