--terminal-width -10 is parsed incorrectly

[rwe]

The dash appears to be interpreted as a flag.

The man page says:

If prefixed with '+' or '-', the value will be treated as an offset to the actual terminal width.

However, executing produces an error.

$ bat --terminal-width -10 foo.md
error: Found argument '-1' which wasn't expected, or isn't valid in this context

USAGE:
    bat --terminal-width <width> --theme <theme>

For more information try --help

Using a positive offset (+10) or fixed value (120) both behave as expected.

As a workaround, combining the option into a single token behaves correctly:
--terminal-width=-10
