Minor tweak for _module completion

[Daniel Qarras <dqarras@xxxxxxxxx>]

Hi,

the attached patch hides backup files (ending with ~, often created unknowingly with emacs by many users) while completing for "module".

(I presume it was ok to use "grep -E" instead of two grep commands, ie, "grep -E" should be supported where zsh can be used? If not, please feel free to modify if needed.)

Thanks!
