Objed maintenance

[Amy Grinn]

Hi Clemens!

First of all, I want to extend my appreciation for your innovative work
on the objed package.  It is by far and away my favorite modal editing
package.

I have been maintaining a fork of objed for about two years; it's
available here:

https://gitlab.com/grinn.amy/objed

I believe my addition of the C-g command and the objed-game tutorial can
be valuable to existing users.  The former allows for quickly entering
and exiting objed and the latter allows users to learn the whole
potential of the package.

I've also made improvements to existing commands such as slurp and barf,
organized the codebase, updated the documentation, and simplified the
build and testing process using eldev.

I would love to get your feedback on any of these improvements, however
I'm aware that this package is not at the forefront of your mind right
now.  In the absence of any activity over the past 4 years, I would
humbly suggest turning the project over to me.

Best,

Amy
