Not sure what you're suggesting.  But (for me) the
point of a command such as `Info-goto-node-web' is
to visit a URL (for a manual node) in your browser
of choice - not to substitute whatever browser we
might think you should use - whether within Emacs
or not.

I'm not saying that's what you're suggesting.  I
don't know just what you're suggesting.  But we
should (1) let users tell Emacs which browser they
want to use by default, for such things and (2)
use that browser by default, for such things.

One reason to open a manual in a web browser might
just be to get HTML rendering.  Another, perhaps
more important reason (IMO), might be in order to
use a non-Emacs web browser.

I chose `G' for `Info-goto-node-web' to correspond
to `g' for `Info-goto-node' - i.e., for "go to".
