Some users would prefer to never suggest corrections at all. For
example, they may want the mistake over with sooner so that they can
issue the correct command, especially on low-end hardware which may take
a while to calculate suggestions.
This updates help.autocorrect to accept the strings "immediate" and
"never" for this purpose, the former assuming the prior behavior of
negative values for autocorrect, and the latter skipping auto-correction
entirely.
