Supress ZSH "no matches found" error

Fixes issue #39

ZSH's default globbing behaviour differs from Bash. If there is no
match, ZSH itself will print the error message.

This means that piping a commantd's STDERR to /dev/null will not
hide it.

By unsetting the NOMATCH option we get a behaviour similar to Bash.
