Log:
  MFC r227769, 227770, 227771:
  
  - Add a note to src/Makefile that explains that 'rm' runs twice because
    thesecond invocation only needs to operate on files with the immutable
    flag set.
  
  - Fix the note in r227769 to be less specific to the immutable flag.
  
  - Replace 'chflags' with 'file flags' in a comment, since 'chflags'is a
    command, not a flag itself.
