Fix whitespace bugs

- Delete trailing whitespace.
- Replace 8 single column spaces with hard tabs.
- Delete lines with consisting purely of blank space.
- Add space between `return` and `(`, per style(9).

Special care was taken to not blindly replace 8 single column spaces
with tabs; doing so could break tools that do strict string comparisons
with camcontrol output.
