This will be possible when you let-bind both `Man-notify-method'
and `Man-async':

  (let ((Man-async nil) (Man-notify-method 'pushy)) (man "bash"))

But what if `man' is unable to get a complete list of all available man pages?
Then you can't read some man pages.  For instance, this happens when
you install a new package with a man page, but Man-completion-cache
is not updated.  This is a very rare problem, and you can still
read the man page by entering its name without completion.
