I think there is some convention about classifying comments.  I don't 
know what it is.  If you want to publish some elisp code to the 
community, it would be nice to follow the convention, but the world 
won't end if you cannot figure it out.

describe-bindings
(I found this with apropos bind, i.e. ESC-x apropos RET bind RET)

When you see the toolbar displayed, what is the value of 
ediff-use-toolbar-p?  It could be that loading ediff sets it back to t 
or somesuch.  (I'm on Windows, and I don't have ediff-use-toolbar-p.)

The first notation lists one file extension.  I'm not sure why it has a "$".
The second notation lists four different file extensions, any one of 
which is for nxml-mode.
