Detailed Description

An RAII class that temporarily undoes part of the current change group.
The sequence:

  {
    ...;
    undo_recog_changes undo (NUM);
    STMTS;
  }

executes STMTS with all the changes numbered NUM and up temporarily
reverted.  STMTS must not try to add to the current change group.

Nested uses are supported, but each nested NUM must be no greater than
outer NUMs.
