PatR ad46090732 fix github issue #734 - ^A crash ...

Issue #734 reported as "parse function" by Meklon2007:  the change
yesterday intended to make ^A work for commands that were preceded
by a prefix was triggering a crash if used after a keystroke that's
not assigned to any command.

'M^A' or '~^A' would segfault by derefencing a null pointer when
checking whether 'M' or '~' was a prefix.  This prevents the check
attempt from doing that, but a better fix would be to not put the
invalid command keystroke into the do-again buffer in the first
place.

Fixes #734
