softwrap: save and restore firstcolumn when replacing text

In do_replace(), replacing text may change firstcolumn if the next match
is offscreen, and replacing text after that will not change it back.  In
order to keep the viewport unchanged, we have to save and restore not
just edittop, but firstcolumn as well.
