Trivial for someone who already knows the code.  Any maintainers out
there listening?  Please add this.  Thanks!

That's cool, thanks!

Zsh masters, can these things related to spell-word be put on the TODO
list?  If there is such a list that is, as I don't see one in the
distribution tree.

It would be nice if the autocorrect that uses the spell-word stuff would
cover spell checking each part of the path for filenames, so it would
cover this example (assumes there are no other files that start with
pas* in the /etc directory):

zsh$ cat /ect/pas<tab>
expands to:
zsh$ cat /etc/passwd

This seems like it would be slow, and given the number of times I hit
"tab" any slowness would likely be very annoying!  ;-)

Bart, mind giving me some examples of how completeinword and awaystoend
work?  I tried setting these and hitting tab in a few instances, but it
didn't seem to change the behavior.  I can see where it would be nice if
COMPLETE_IN_WORD worked for spell-word, but I don't see it actually
affecting anything right now.

Thanks,

Matthew.
