Title:
  fuse should add uhelper= mount option to allow unmounting with umount

Status in fuse package in Ubuntu:
  Confirmed

Bug description:
  Hi,

  mount -t fuse or -t fuse.sshfs calls mount.fuse and libfuse based fuse
  wrappers like sshfs or archivemount use fuse_main, but these mount
  points can't be unmounted with "umount".

  There's provision to umount fses which aren't in fstab by non-root,
  but this requires setting an "uhelper" program.

  I've tried this:
  * mount with archivemount or mount.fuse as a regular user
  * edit mtab and add "uhelper=fuse" in the mount options
  * create a /sbin/umount.fuse shell script which just execs fusermount -u "$@"
  this allowed me to "umount" as a regular user; I believe fuse should do so.

  Also, why trying this out I noticed that fuse is looking for user=xyz
  in mtab, but can't cope with this not being the last option; this
  probably needs to be fixed if more options get appended to mtab.

  Cheers,
