Drush fails if machine name of new theme ends with "_basic"

Funny story, and not important at all, but I just found out.

If you use drush to create your basic-based theme, and the machine name ends with _basic, then drush fails:

$ drush basic-install
Checking for npm...
npm was found.

I don't have time to debug now, I may check again in the future. I just drop this here as a reference point.
(Or maybe there are already instructions about this but I missed them?)
