getRowFromIdPos returns row shifted by 1 (we count internally from 0). The function still doesn't work properly looking at the the comments of the original writer (last *nonempty* row), but its hopefully better now. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@34172 a592a061-630c-0410-9148-cb99ea01b6c8
