Provide a mechanism for function help to include information about what it returns #1402

The current function help is an improvement over R2. It would be even better if there was a structured way to include information on what the function returns.

I'm sure there are many ways that this could be achieved. One would be to have a dummy returns refinement:

verify-numeric: func [
 "Verifies a string is numeric"
 number-string [string1]
 /local
  i
 /returns
  {true if the string contains only digits
   otherwise the position of the first non-digit}

This has been planned for a while... there's a special form for it. More later.
