I've written a patch to make epa-list-keys insert text to explain
the cryptic letters that come first in each line.
This function epa--insert-keys is called from other places
and I don't entirely understand how they are supposed to interact.
I added comments explaining what I think that does
but I am not sure of them. Is there an expert who can verify
this code and the comments?
If it is correct, please install it for me.
