Excellent!  It's easy to use, so you who love the w3m-lnum feature
should try the new behaviors soon.  I've already installed your
changes to CVS[1].  `C-c C-l' is what those who have never used
it do first.

Agreed.  I also agree to make the `C-c C-l' key be bound to
`w3m-linknum-follow' by default.  I.e., abolish `w3m-go-to-linknum'
and make indexing of forms the default.  Furthermore, I think it's
convenient if `w3m-read-int-interactive' turns off the
`w3m-link-numbering-mode' mode by the `C-c C-l' key input.  IOW,
making the `C-c C-l' key the toggle switch.  WDYT?

Thanks again.

[1] I've slightly changed your code.  Let me know if there's any
oddity.
