Trailing white spaces

[Piero Campalani]

Trailing white spaces should be cleared out from the code sources, and it would be better done in some dedicated patch.

It is good practice to make sure no new trailing white-spaces are re-introduced when formatting a patch.

E.g.

• shell: sed -i 's/[ \t]*$//'
• vi: :%s/\s\+$//g

Yes we should do it in a dedicated patch, otherwise it's hard to review patches because so many changes are just whitespace.
