Merge in two patches from Dave Cinege:

Browse Source 
the first is a cleanup of tar --exclude
    the second changes mount so mtab works more as it should, and
    also allows mount to use the traditional short form (i.e.

* 2000-01-12 Ben Collins <bcollins@debian.org>, Borrowed utils-linux's
* mount to add loop support.
*
* 2000-04-30 Dave Cinege <dcinege@psychosis.com>
* Rewrote fstab while loop and lower mount section. Can now do
* single mounts from fstab. Can override fstab options for single
* mount. Common mount_one call for single mounts and 'all'. Fixed
* mtab updating and stale entries. Removed 'remount' default.
