Fix `--force` behavior in `remove`.
Fix `--force` behavior in `remove`.

The `--force` option is passed to the function in `$_COMMAND_ARGV`,
which means that assigning arguments from positions in this array leads
to unexpected behavior depending on where in the argument list `--force`
is included. As a result, the `remove` function must parse the
arguments, removing the `--force` argument before assigning function
arguments to local variables.
