bash_completion: small cleanup and bugfix

_hg_count_non_option wasn't taking global options into account
while counting non-option arguments.

It also used only its first argument.

#!/bin/sh

hg init
mkfifo p

hg serve --stdio < p &
P=$!
(echo lock; echo addchangegroup; sleep 5) > p &
Q=$!
sleep 1
kill -HUP $P
sleep 1
ls .hg
