_values again and new _ifconfig

[Oliver Kiddle <okiddle@yahoo.co.uk>]

The patch adds completion for ifconfig. ifconfig varies across systems
so there is plenty of scope for updates to it to handle more systems.
I've put completion for network interfaces in a separate function.

_ifconfig shows up another limitation of _values. If values are
separated from their arguments by a space (unquoted), it'll go on
completing more values instead of the previous value's arguments.

What I think is that -S ' ', should mean that the separator is a quoted
space and that with -w, the default for -S should not be '=' but also
separate words. And, -S should be another letter but I'll leave that
argument for when the suffix handling discussion comes up.

I also noticed a few cases where the description had been forgotten
from an _values call. I also think it might be better to ditch that
argument to _values and require _description to be used.

Oliver
