Subject: [PATCH] softwrap: save and restore firstcolumn when internally
spell-fixing text
In do_int_spell_fix(), spell-checking text may change firstcolumn if
the next match is offscreen, and spell-checking 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.
