gvfs-mount -u tries to mount, unclear --help

[Martin Pitt]

I have my USB stick automounted by nautilus/gvfs. Trying to unmount it gives:

$ gvfs-mount -u -d /dev/sdb1
Error mounting /dev/sdb1: Device /dev/sdb1 is already mounted at `/media/martin/4805-C45B'.

Apparently it tries to mount it again instead of unmount. Same with using --unmount.

udisks works fine FTR:

$ udisksctl unmount -b /dev/sdb1
Unmounted /dev/sdb1.

Apparently the --help output is a bit misleading, you are not supposed to specify a device with -d. But if you try without:

$ gvfs-mount -u /dev/sdb1
Error finding enclosing mount: Containing mount does not exist

Both errors happen exactly the same with current git head, so regardless of whether or not -d should be used, something is wrong.

A variant that does work:

 $ gvfs-mount -u file:///media/martin/4805-C45B

so apparently gvfs-mount does not support unmounting by device file, only by URI.
