Extensions to standard library `emacs-lock.el’
Adds the following features:
- When locking any buffer, you are prompted for a little note that helps you to remember why you locked the buffer.
- If any buffer prevents Emacs from exiting, pops up this buffer and displays your note, if there is one. Also displays the note if you try to kill any locked buffer.
- Adds a mode-line indicator which displays a capital “L” for locked buffers (and a lowercase “l” for non-locked buffers, if this is enabled. You can deactivate this indicator if you don’t want it.) If you move the mouse over the indicator, the locking note is displayed.
