Hello,
Please see below a small patch proposal for a new configure option to move
the ^D (EOT) behaviour to a different key (^Z which is currently
unassigned), which allows keyboard ctrl-D to act as delete-char.
I did this because I found my muscle-memory from bash, emacs etc. caused me
to hit CTRL-D too often while editing lines. I find it convenient to have
CTRL-D act as expected in concert with CTRL-A,E,K,P,N.
If CTRL-Z is not good, perhaps it could be assigned elsewhere but I didn't
see how to easily assign to a less-common key that isn't already in use.
Cheers,
-Russ
