[patch] groups with spaces

[Matthew Martin <phy1729@gmail.com>]

While most utilities to disallow groups with spaces, LDAP seems to have
no such qualms. Patch below to handle spaces in _groups. (Apologies if
it's mangled; my normal mail setup is currently blocked.)

_chgrp tries to be helpful and only suggest a user's groups for
effectively non-root users. Both groups and id -Gn separate groups by
spaces, so their output can't distinguish between two groups and
a single group with a space in it. Should there be a _user_groups type
that can

${${(f)"$(getent group $(id -G))"}%%:*}

along with whatever OS X and YP need?
