Subject: [PATCH] softwrap: realign start-of-screen when redoing an automatic
 hard-wrap

Redoing an automatic hard-wrap while one or more chunks of the affected
line are offscreen, can leave 'firstcolumn' with a value that doesn't
fit the situation.  So, make sure that it has a valid value.

This complements the previous commit.

This fixes https://savannah.gnu.org/bugs/?65611.
The issue was reported by `correctmost`.

Bug existed since version 2.8.6, commit e375995d.
