man.vim: :Man! operates on buffer contents (#9139)

Browse Source 
mandoc may not handle quoted MANPAGER arguments correctly. E.g. with
    export MANPAGER='nvim -u NORC -c "set ft=man"'
mandoc treats `"set` and `ft=man"'` as separate tokens.

To workaround that, provide :Man! so that MANPAGER can avoid quoting.
