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?
