lvremove documentation dangerously misleading

Bug Description

lvremove help messages are dangerously misleading. Let's say you have volume group "gr" and volumes "vol1", "vol2".

The command: "lvm lvremove --help" returns the following:

  lvremove: Remove logical volume(s) from the system

 [-A|--autobackup y|n]
 LogicalVolume[Path] [LogicalVolume[Path]...]

But that's not what it does. When calling with one parameter "vol1" it says:
  Volume group "vol1" not found
  Skipping volume group vol1

Ok... not exactly what I expected, but it's just misleading. Where it goes really bad is if you try this: create volume "gr" in another volume group. According to the docs "lvm lvremove gr" should be expected to remove it, right?

# lvm lvremove -f gr
  Logical volume "vol1" successfully removed
  Logical volume "vol2" successfully removed

Even though the help message mentions path, it never says it works on whole volume groups, which can cause lots of problems given unfortunate naming.
