This patch looks very promising. I've so far only tested the patch on 
a physical computer while logged in by mosh.

Hitting C-r, then typing "cvs" to lookup a command like 
"cvs diff -u 2>&1", and hitting the enter key would previously display 
"", but with the new patch in effect the whole command is displayed 
when hitting the enter key.

I've compared this patch to 4.3.11 as installed on said computer, and 
the patch does work for me.

I'd like to test the patch on a few of my FreeBSD VMs at home later 
today. I'll keep you posted.

Great work!
