[conan center] trailing white-spaces

[SSE4]

from https://github.com/conan-io/conan-center-index/pull/1375/files#r409740469 /cc @uilianries I am very tentative about this, might be super annoying

[Croydon]

Agreed, probably too annoying for too little advantages

[uilianries]

I think we can iterate over each line and check .endswith(' ')
