Severity: normal

The `Electric-command-history-redo-expression` command is autoloaded
but it doesn't seem to do anything:

0. emacs -Q
1. M-x command-history RET
2. M-x Electric-command-history-redo-expression RET

Since this has seemingly been broken for a long time, and no one has
noticed, perhaps echistory.el is simply unused and should be obsoleted?

I find nothing about this obscure command online or on the mailing lists.

I think you need

M-x electric-command-history

for things to work. Iʼve never used it, and trying it just now itʼs
excessively intrusive and obnoxious with its bindings. We can fix
that, but if nobody is using it thatʼs not worth it.

Aha, right.  That command on the other hand is not autoloaded, curiously
enough, so you need to say this first:

    (require 'echistory)

Agreed on all of the above, thanks.

Similarly, I can't get ehelp.el to actually do anything.  Maybe it does
something, but the instructions don't work, or at least have no effect
from what I can see.

Another library Iʼve never used, and judging by `vc-annotate' not many
others do either (or itʼs just perfect as it is 🙂)

I have now moved echistory.el to lisp/obsolete.  Let's see if anyone
protests against this change, meanwhile I'm closing this bug report.
