|  Function     :  ccd_patch

|  Description  :  This function checks if the element is to be patched

|
|  Parameters   :  globs - entity/code information (containing nesting stack)
|                  validflag - set if called from valid flag coding
|
|  Return       :  FALSE if real coding function is to be called, TRUE otherwise
|                  if validflag is set, TRUE means, the element is identified
|                  in the patch list
