The no follow option will allow user to distinct mount points from symbolic
links pointing to them. Arguably this is pretty pedantic option, mounting a
device or bind mount to a directory via symlink does not have or cause any
issues.

Consolidate --help and --version descriptions. We are
now able to align them to the other options.
We changed include/c.h. The rest of this patch was
generated by sed, plus manually setting the right
alignment numbers. We do not change anything but
white spaces in the --help output.

BSD/Linux systems stick major/minor/makedev in sysmacros.h. Newer Linux
libraries have been moving away from including sysmacros.h implicitly via
sys/types.h, so include it directly.

This adds a concise description of a tool to its usage text.
A first form of this patch was proposed by Steven Honeyman
(see http://www.spinics.net/lists/util-linux-ng/msg09994.html).

Returning straight after print_devno() makes the code to be more obvious
and removes need for long else statement.

commit 04f087ec didn't take into consideration that mnt_fs_get_target()
could return an error, and would therefore show false positives, such
as:
$ mkdir foo; mountpoint foo
foo is a mountpoint

zhi@debian-lizhi:~$ mountpoint /sys
/sys is not a mountpoint
zhi@debian-lizhi:~$
The problem is in mountpoint.c, function dir_to_device(), which uses 0 as an
error return value, but for sysfs 0 is its device number:
zhi@debian-lizhi:~$ cat /proc/self/mountinfo
14 19 0:0 / /sys rw,nosuid,nodev,noexec,relatime - sysfs none rw
15 19 0:3 / /proc rw,nosuid,nodev,noexec,relatime - proc none rw
My change is on dir_to_device, seperating device number from return value.

There's only one condition for which we declare success, but many for
failure. Initialize rc as failure and set to success on this single
condition. In all cases, jump to a label to exit instead of exiting
immediately. This will be used later on to ease cleanup of any heap
allocations.

The string returned from this function was never of much use other than
to stat the path when the user requested a major:minor pair beyond the
true/false exit. Save some processing and directly returning the dev_t
on success, and an impossible value on failure.
[kzak@redhat.com: - use 0 as dir_to_device() return value on failure]

This is libmount based re-implementation of the mountpoint(1) command.
The original implementation is maintained in sysvinit suite.
The mountpoint(1) in util-linux is not enabled by default (for now) --
use --enable-mountpoint to enable the util.
