Hi Lars,

Thanks for this.  I've actually implemented a more general solution
with default support for the view-mode case, so I'll revert your
changes when I merge the scratch/so-long changes.

https://git.savannah.gnu.org/cgit/emacs.git/commit/?h=scratch/so-long&id=6edeae3b4b7dd5105c9cf0dc0560d4c2c96a85bd

I don't see a problem with leaving your change in place for the interim,
though.  It doesn't handle the `so-long-revert' case, but there's no
need to address that as my changes will deal with it.


-Phil
