man: User=, Group= *never* work for mount units (#7602)
Old text:

However I recently learnt the following:
> The mount program does not read the /etc/fstab file if both device
> and dir are specified.
Therefore, if both device and dir are specified, the `user` or `users`
options in `fstab` will not have any effect. Run as a normal user,
you will always see
mount: only root can do that
Fix the explanation in the man page.
Also make sure to markup User= and Group= with <varname>.
