- OOPS, line up link/unlink/rename check if conditional with
|
||||
top if conditional. Option -l has been broken for 9 versions,
|
||||
no one noticed?!
|
||||
- Added saving perms at end of link so we can apply them to the
|
||||
new file if --nofollow is used.
|
||||
- winio.c:
|
||||
edit_add()
|

- Off by one display error (fix by Rocco Corsi).
