Every time I read that passage of the elisp manual, I, like the
original poster, interpreted it to mean C-c ANY-SEQUENCE, not what Len
interpreted it to mean and the authors probably intended, C-c
ALPHABETIC-CHARACTER.  This is a bug in the manual, in my opinion.  It
should emphasize that it is referring only to alphabetic characters.
This subtlety is not clear enough currently.
