[RP] dtach and ratpoison

[Björn Lindström]

I'd like to use dtach (http://dtach.sf.net/), but I'm having some
trouble with it and ratpoison.

When reattaching to a program, it apparently sends a WINCH signal to the
program. Somehow, this doesn't lead to the right thing when I try it in
ratpoison. The screen ends up blank. A ^L fixes this, but it's annoying,
and it depends on the program used to support it.

Any ideas on how to make this work, or suggestion on how dtach _should_
handle this?
