Hi, thanks for the typo fixes. But since that file is copied from GNU units, I'd rather not deviate from the original any further - we do patch the file, but that's just to make the contents more compatible with the format that the load script is expecting.

Could you try to submit these fixes directly to GNU units? (Afaict they don't use git, but they do accept patches.)
