I love it when I say "This shouldn't be too hard; somebody may want
to do a patch", with just a vague implemention idea in my head, and
a patch magically appears with even a better design than I had in
mind when I said it [*1*] ;-)

Having said that, I wonder if we could do a bit better.

   $ git -c help.autocorrect=1 whatchange --help
   WARNING: You called a Git command named 'whatchange', which does not 
exist.
   Continuing under the assumption that you meant 'whatchanged'
   in 0.1 seconds automatically...
   No manual entry for gitwhatchange

We are guessing that the user meant "whatchanged"; shouldn't we be
able to feed the corrected name of the command to the machinery to
drive the manpage viewer?

But does it cope with the Guides? Should it cope if spelt that way?

git help revisions
git revisions --help

?

I suspect that the former should work, but not the latter, as a reasonable 
approach. I just haven't checked.

The other moderately low hanging fruit is to do the (full) list of guides as 
part of 'help'.
