Fix #22832: Code cleanup and some simplification, documentation fixes (patch by gaben)

There should not be any functional changes in this patch; it is intended to do
the following:

  • Simplify and cleanup code (example: Arrays.asList(item) -> Collections.singletonList(item))
  • Fix typos in documentation (which also corrects the documentation to match what actually happens, in some cases)
  • Property svn:eol-style set to native
