This explanation isn't wrong, but it conflates two separate features,
thus is confusing. The $(basename <branch>) DWIM'ing from the short
form of the command, "git worktree add <path>", doesn't actually have
anything to do with the DWIM'ing added by 4e85333197 ("worktree: make
add <path> <branch> dwim", 2017-11-26), which merely tries to DWIM a
remote-tracking branch of similar name to $branch (whether $branch
came from long or short form of the command), so I confused the issue
unnecessarily by talking about the short form.
