anchor.diff:  For POSIX-style short options (like `-f` or `-c`), the option parameter may be attached to the option,
   or it may be separated by a space or the _separator string_ (`=` by default).
   That is, all of the below are equivalent:
  -[source,java]
  +[source,bash]
   ----
   <command> -foutput.txt
   <command> -f output.txt
  
positive.code: }
  ----
  
  
  === Automatic Parameter Indexes
  ==== Automatic Indexes
  
negative.code: 
  Long option names (like `--file`) must be separated from their option parameter by a space or the
  _separator string_ (`=` by default). That is, the first two below examples are valid but the last example is invalid:
  [source,bash]
  ----
  // valid (separator between --file and its parameter)
  <command> --file output.txt
