A pick inside a multiline wall found the band between the wall's lines
as the outer boundary, but the rooms the inner lines enclose were
dropped as islands: island_curve accepted lines, arcs, polylines and
splines, not multilines. The rooms were filled along with the walls. A
multiline's lines can now make up an island like the other open curves.

Inserting a DWG/DXF as a block merged its layers, linetypes and text,
dimension, multileader and table styles, but not its multiline styles.
A drawing that brings its wall styles in by inserting a library file
(AutoLISP add-ons do this: INSERT walls.dwg, ERASE the reference, then
MLINE with one of its styles) got "Cannot find multiline style". The
styles now merge like the other tables: a name the drawing already has
keeps the drawing's definition.
