Good, thanks.

OTOH, it's just the same behavior as under POSIX where environment
variables are not provided via xrm but directly (and -Q does not
override them).  For HOME settings, I think it's TRT.  For other
variables, it's less clear, but I think it's OK for now.

I think it *should* obey myresource.  I don't know how to implement that
behavior, tho.
