Subject: [PATCH] fix(_comp_expand_glob): set LC_COLLATE for the sorting order

In sourcing the file `000_bash_completion_compat.bash` located in
/etc/bash_completion.d, we rely on the sorting order of the pathname
expansions.  However, this can be broken by locales that collates
digits after the alphabets.  We set LC_COLLATE to C and unset LC_ALL
(which might override LC_COLLATE) while keeping LC_CTYPE.
