Hrm.  The direct answer is "no" but:

That would certainly seem logical.  Also it seems strange to load up
the command tables and check them for proper spellings when the word
that is being checked is not in the command position to begin with.

What this patch does is reset the incremental path search in the event
the correction is rejected.  That allows whatever hashing options the
user has specified to kick in at the time the path is searched during
command execution, rather than having to test them all here.
