That has revealed a bug in Colortemplate, which has been fixed in the current master.

I have rebuilt the Lightline script for Gruvbox 8. Currently, the same template (_lightline) is used both for dark and light background. If the code needs to be differentiated, two templates (say, _lightline_dark and _lightline_light) could be defined.

I do not use Lightline, so I haven't checked how it looks. Please review, and if further changes are required, let me know (or, even better, open a pull request).
