Woah. My whole life is a lie …

You know there's something wrong with a library when an X.org
developer questions its general sanity ;-)

Joking aside, this does mean that strtod could be a good option when
parsing the single value. The check would be more verbose though, so I
think I'll stick with sscanf.

I'll add the positive check for both scale and gamma and respin the patch.
