- Update the previous line as well as the current one in case we
have moved beyond COLS or back from COLS, patch submitted
by Ryan Krebs.
die()
- Now creates .save file using variable-length strings. Also
calls write_file with tmp == 1, which happens to do exactly what
we want (ignore symlinks and use mode 0600).
handle_sighup()
- Now calls die instead of writing on its own and exiting normally.
- search.c:
do_replace_hilight()
- New function, displays the currently selected word as hilighted
