[PATCH] worktree: accept -f as short for --force for removal

[Stefan Beller <sbeller@google.com>]

The force flag is very common in many commands and is commonly
abbreviated with '-f', so add that to worktree removal, too

As a side note:

 $ git worktree add ../test HEAD^
 $ cd ../test
 $ make
 $ git worktree remove test
 fatal: working trees containing submodules cannot be moved or removed
 
 (This is on git.git, which does have submodules, but they should not 
 be relevant here? Instead we rather want to point out files left over.
 Not sure. I also plan on having worktrees and submodules to work well
 together eventually)
