- Allow --tiny and --multibuffer to cooperate (who the heck
would want this is beyond me but ;-). Changes to
configure.ac, global.c, , (David Benbennick).
+ - Change to openfilestruct for multibuffer mode by DLR.
+ New functions nano.c:make_new_opennode(), free_openfilestruct(),
+ delete_opennode(), unlink_opennode(), splice_opennode(),
+ new struct openfilestruct in nano.h.
- configure.ac:
- Define NDEBUG to silence asserts (David Benbennick).
- files.c:
