man integration with tramp

[Ergus]

Hi:

Do we have any functionality to support man in tramp mode to access man
pages in the remote node?

The actual implementation of man has call-process so I suppose we
don't. But it doesn't seems too complex to do.

Suggestions?

Should we add a different command, a configuration option or you think
it is not a good idea? Is there anything special to take into account
and I am ignoring so far?

Best
