Formatting: miscellaneous.

This patch fixes a few other whitespace and formatting issues which
were pointed out by the bulk-reindent or which I spotted in passing,
some involving manual editing to break lines more nicely.

I think the weirdest hunk in here is the one in windows/window.c
TranslateKey() where _half_ of an assignment statement inside an 'if'
was on the same line as the trailing paren of the if condition. No
idea at all how that one managed to happen!
