 I have *five* macros that do that, in different ways, and none
 depend on having space as a wordset character.  Three handle
 various quoting styles (BlueWave, Speed-Fido, Speed-Qwk) I use,
 and two handle unquoted text, depending on whether I want
 autoindent to work now or not.  For your purposes, the easiest
 thing would probably be to do something like
 Left() CReturn()
 tho my unquoted text pair are more complex
       Set(Insert,1) CReturn() Set(Insert,0)
                  EndLine() Right() MarkStream() WordRight()
                  Left() Cut() GoToColumn(74) WordLeft()
  MarkColumn() EndLine() MarkColumn() Cut() WordRight()
                  Paste() GoToBlockEnd() Right() UnMarkBlock()
 Conversely, you might make variants on WordLeft.  I have ones
 that stop at the end of words instead of the beginnings, and
 and at the end of non-space strings.  You could easily have one
 that simply stuck a PrevChar() after the WordLeft().
