/*
* The MARK and LMARK structures define positions in the file. There are
* two structures because the mark subroutines are the only places where
* anything cares about something other than line and column.
*
* Because of the different interfaces used by the db(3) package, curses,
* and users, the line number is 1 based and the column number is 0 based.
* Additionally, it is known that the out-of-band line number is less than
* any legal line number. The line number is of type recno_t, as that's
* the underlying type of the database. The column number is of type size_t,
* guaranteeing that we can malloc a line.
