Period

   DSR routinely inserts an extra expandable space after a period
   (.), colon (:), question mark (?), or exclamation point (!) that
   is followed by the usual end-of-word space.

   The Period flag (+) lets you specify the extra space following
   other characters.

   If the flag is turned on and .FILL is in effect, an extra
   space occurs when the flag (+) is inserted directly after the
   character. You must, however, insert the end-of-word space after
   the flag if it is to be effective.

   For example, if you have a complete sentence enclosed in
   quotation marks or parentheses, you may want an extra space after
   the closing quotation mark or parenthesis.
