worktree: add can be created from any commit-ish

Browse source 
Currently 'git worktree add' is documented to take an optional <branch>
argument, which is checked out in the new worktree.  However it is more
generally possible to use a commit-ish as the optional argument, and
check that out into the new worktree.

Document that this is a possibility, as new users of git worktree add
might find it helpful.
