improvements for metapackages
I had a look at base-devel's PKGBUILD today and wondered why it has a license=() array even if there is no content to license.
Someone on IRC said that it could be because the author wanted to suppress namcap warnings.
So I tried to fix that and created a check whether a given package is a metapackage and exclude missing licenses and unneeded deps from there.
I think there could be two main ToDos:
- 
testing to avoid regressions 
- 
Coding style (will do in the end) 
Looking forward to your feedback!
