Any switches supported by the 'man' command you have installed, I
think.

It does work: it produces all of the man pages by that name, in all of
the sections.  You just need to go from one to the other with M-n and
M-p, as "C-h m" tells you.

The one you have installed.  man.el just invokes the first one it
finds on PATH.

No, 'man' is not a pager.  It is a program that formats and displays
manual pages.  A pager is a program like 'more' or 'less'.  At least
that's what I would call a "pager".
