Whitespace cleanup

Minor change to the perl postprocessing script and resulting changes to
the affected source files.

This deals with two issues:
- "foreach"-like structures were not always treated correctly
- some longer calculations that ended on "+ constant" were reformatted in
  a rather unatractive manner

In one source file (divelist.c) I ended up adding braces to the sources...
trying to cascade the indentation further down without having the block
there seemed a lot more trouble than it's worth.
