I use tui mode often, but single key mode, not so often.  Anyway, see my
comments below, but note that I can't approve patches.

This seems useful indeed.  Thanks!

If the only command gdb knows starting with 'q' is "quit", what
is the use?  What is it preventing you to type?  Maybe
a target/host specific command?  At least on cygwin 'q' is not
ambiguous.  On the other hand, if you're in in single key mode, and
want to type "quit", you have to type "qquit", since the first 'q' is
eaten, else you'll end up typing "uit" :)  I guess it's a matter of
personal taste either way.

This is trivial indeed.

Seems like a hack to me.  What about not setting TUI_SINGLE_KEY_MODE
in the first place, if gdb is in the middle of a possibly length
command?  The attached works for me, but I didn't regtest it.  Is
this usage of immediate_quit ok?

In single key mode, I can start to type 'b' for a breakpoint, and
then decide I want to scroll to see at which line I would want to place the
breakpoint at using up/down.  If I want access to the history, I can either
use c-p/c-n, or use c-x o to switch focus to the command line, and
then use up/down.  With your patch, if I already started typing 'b',
I'll have no way to scroll, other than deleting what I've already
typed, will I?
