Caption string: Escape status

[Ben Love]

I'm looking for a way to have a visual cue (preferrably in the status
line) to know when the escape sequence (C-a) has been pressed.  This
would be particularly useful when nesting screen sessions.  I've
looked through the man page for the string escapes sequences but
haven't found anything that does something similar.

I've considered creating a patch to add a new string escape sequence
that would return the state of the escape (similar in function to %F).
But first I wanted to make sure that this wasn't already possible
through some other means.

Ben
