another batch of formatting

another batch of formatting

Same sort of stuff as before:  some continuation lines with operator
followed by end of line comment (only a few files with those still to
go...), plus tab replaced by spaces in comments, excess parenthesis
removal for return statements, and force function name to be in column
one in function definitions:
  type name(args) /* comment */
  argtype args;
  {
to
  /* comment */
  type
  name(args)
  argtype args;
  {
I've been spotting those by eye rather than rexexp, so probably missed
some.
