@ -57,6 +57,12 @@ CVS code -
|
|||
- 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
