Wow, this is a blast from the past. I think this was one of my first
contributions to Git, and indeed:

I agree with the rest of the patch, but is this true (no pun intended
;-))? I thought that we might canonicalize "yes" to "yes" if the value
we are asking about is already something other than a literal "true" or
"false", but I don't think we do:

    $ git.compile -c foo.bar=yes config --type=bool foo.bar
    true

So I do think that it is worth saying "you can spell 'true' as 'yes',
'1', ..." in the documentation, but I don't think that it is correct
that we'll canonicalize "yes" to "true" in the case described here.

Sorry that this took me so long to respond to. I think I must have
missed it when you wrote it and I only noticed it today while cleaning
up old emails.

Thanks,
Taylor
