# we had a bug where pasting on an empty line right after a forced
# linebreak would think "oh, I'm in an empty element, I'll just change the
# linetype of this line and be done with it", which is wrong, because the
# linetypes of the lines above were not changed, and now you had an
# element with multiple different linetypes. the right thing to do is not
# change the linetypes at all unless the entire element is empty.
