feat(show): allow unescaped negative patch offsets

jpgrayson · jpgrayson · commit b42de59c8edd · 2023-12-26T13:00:40.000-05:00
This allows, for example, `stg show -1` to show the patch preceding the
topmost patch. Previously, a negative relative patch offset would have
had to been escaped, e.g. `stg show '\-1'` or `stg show \\-1`.
