Whitespace only change, translators please ignore.

The FAQ was full of lines longer than 80 characters, lines broken into
two chunks of 45 characters, irregularly wrapped, sections mis-spaced,

I avoided all the code listings of course, so as to not screw up
formatting.

Tested by: make, re-reading the whole FAQ

What do you mean, I have insomnia?"
