man.vim: workaround for 'cscopetag' #11679

Browse Source 
The old `:Man` implementation would take either the word under
the cursor, or the argument passed in, and load that as a man page.

Since we now use 'tagfunc' and look for all relevant man-pages, if
your system has several (i.e. same name, different sections), we return
several, giving the user an option.

This works for most tag commands except `:tjump`, which will
fail if there's multiple tags to choose from. This just happens to
be what the cscope code uses (it actually attempts to prompt the
user, but this fails).
