Trivial changes: whitespace and modes. Remote whitespace at the ends of lines. Remove blank lines from the ends of files. Change modes on source files so that they are not executable. Signed-off-by: Dan Cross <cross@gajendra.net>

awk: split record into runes for empty FS (#292) awk was splitting records into bytes instead of runes for empty FS. For example, this was printing only the first byte of the utf-8 encoding of é: echo é | awk 'BEGIN{FS=""}{print $1}' The change just copies how the `split` function handles runes.
