- Patch 7.3.449
- Problem: Crash when a BufWinLeave autocommand closes the only other window.
- (Daniel Hunt)
- Solution: Abort closing a buffer when it becomes the only one.
- Files: src/buffer.c, src/proto/buffer.pro, src/ex_cmds.c, src/ex_getln.c,
- src/misc2.c, src/quickfix.c, src/window.c, src/proto/window.pro
