HTML and @cartouche

[Simon Josefsson]

I use something like

@example
@cartouche
$ shishi simon@@JOSEFSSON.ORG
Enter password for `simon@@JOSEFSSON.ORG':
simon@@JOSEFSSON.ORG:

$
@end cartouche
@end example

in a manual, but makeinfo --html flows the text, as can be seen on
<http://www.gnu.org/software/shishi/shishi.html#User%20Manual>.  It
looks fine in info and ps/pdf.

* The output should be consistent across html, info and ps/pdf.

* Preferably fix the HTML version instead of info/ps/pdf, I kind of
  like the output (except flowing).  If there is another recommended
  way to write a shell snippet example like the above, please tell.

Thanks.
