Correct several coding convention violations around white-spaces:

  ERROR: spaces required around that '=' (ctx:VxV)
  WARNING: Missing a blank line after declarations
  ERROR: "foo* bar" should be "foo *bar"
  ERROR: "(foo*)" should be "(foo *)"
  WARNING: Block comments use * on subsequent lines
  WARNING: Block comments use a trailing */ on a separate line
  WARNING: please, no space before tabs
  WARNING: Missing a blank line after declarations
  ERROR: open brace '{' following struct go on the same line
  ERROR: that open brace { should be on the previous line
