[packagekit] Developers: Whitespace!!

[Richard Hughes]

Developers, please do:

chmod +x .git/hooks/pre-commit

in your git checkouts of gnome-packagekit and PackageKit.

This will enable some simple checks to stop things like trailing
whitespace and other checks. Every time I merge different branches, I
have to fix up all the whitespace conflicts.

Please also switch your editor to trim trailing whitespace if possible.

Thanks!

Richard.
