Do some whitespace cleanup

The previous commit was a patch from Lubomir, which also had some
whitespace fixes (to go with some new whitespace bugs to replace them)
in it.

I removed the whitespace changes from that patch (don't mix whitespace
fixes with other fixes, unless they are on the same lines!) but decided
to look for other whitespace issues, and this is the result.

I left the non-C files alone, some of the spec and script files also
have whitespace at the end of lines etc.
