I think it works well now.

And this also works well now.

I wonder however: why did you add that `shell-quote-argument' wrapper?
I think there is no shell involved.  It doesn't seem to have an effect
here, but I'm not sure if there are not more problems possible like the
one involving the empty string.

Or do you expect that some people might set `manual-program' to
something involving a shell?


Thx,
