Subject: [PATCH] continue long values using \linebreak notation; this is done
 in conjunction with a change to morkParser::ReadValue()
which will correctly
 interpret this notation.  Note this is
technically a format change in the
 sense that old versions
of Mork will not read such line continuations
 correctly; but
the change is forward compatible so folks should not notice.
