Does that work _without_ specifying 'user-position'?

It seems we have to add a 'user-position' and/or 'user-size'
specification when parsing geometry specifications.  I have no idea
what happens when -g and X resources get mixed.  Does -g work when you
specify a non-nil 'user-position' in your X resources file?

Also as far as resources are concerned we automatically add a
'user-position' and a 'user-size' parameter when a 'top' or 'left'
resource has been specified.  We do nothing when just a 'width' or
'height' resource has been specified.  I don't understand the
rationale of that and it never has been explained anywhere.

Hopefully.
