   Thanks very much! Committed. Now the interesting patches are coming :)

Bob, please make sure there are no regressions from your patch before
you check things in.  I now get:

FAIL: gdb.base/default.exp: tty
FAIL: gdb.base/help.exp: help tty

because the output of the tty command changed.  In the past we had:

(gdb) tty
Argument required (terminal name for running target process).

whereas now we have

(gdb) tty
Argument required (filename to set it to.).

I don't really consider this an improvement...
