No, I'd forgotten the exact circumstances.  However, as I mentioned in
another part of the thread, there's something I missed as well, which
is that if you ^C all the way out of _main_complete, some interesting
(if not always important) bits of state don't get restored.

If we stick with the TRAPINT(), then we need this ...

diff --git a/Completion/Base/Core/_main_complete b/Completion/Base/Core/_main_complete
index 91b68fe..bc63e83 100644

... and we also need an always-block or something to cover cleanup,
which may mean rearranging other parts of _main_complete.

Or we could do this, which stops the matcher-list and completer loops
(and any tag loops or the like that are also in play) and then does
the rest of _main_complete as usual:
