wrapping: trim any trailing blanks when cursor goes to next line

When typing a space causes both the succeeding word and the cursor to
be pushed to the next line, then this space (and any contiguous ones)
does need to be snipped (when --trimblanks is in effect).

This fixes https://savannah.gnu.org/bugs/?56180.

Bug existed since version 2.9.3, commit 91073be4.
