The check for a file's existence within the worktree in add function is useless.

[hanyujie2002]

In the add() function, a file's existence within the worktree is checked.

	if not (abspath.startswith(worktree) and os.path.isfile(abspath)):
	raise Exception(f"Not a file, or outside the worktree: {paths}")

However, this check is redundant because it has already been performed in the rm() function.

	if abspath.startswith(worktree):
	abspaths.add(abspath)
