It is simpler and avoids code duplication (or overhead of fork->exec) by keeping umount code in a single binary along with the mount code. Mount code uses umount to handle certain fail cases. It also makes sense to keep single binary for all the versions of the NFS, as opposed to having seperate binaries mount.nfs and mount.nfs4, since the code falls back to lower version if mounting with v4 fails. Adds two man pages - mount.nfs(8) and umount.nfs(8).

sounds good.

I went with the GNU Autoconf Manual ;), 
http://www.gnu.org/software/autoconf/manual/autoconf-2.57/html_mono/autoconf.html#SEC130, 
which says --with-foo, when external program foo is to be used, and 
--without-foo otherwise. But I know, it sounds rather odd. I think, I'II 
change it to --with-mount.
