[feature] Add edscript as a shortcut for running ed with script?

[Artyom Bologov]

Hi y'all,

I'm using ed for scripting text modification lately. And what often bugs
me is that scripting is so inconvenient with ed. To edit a file with a
script taken from another file, one has to do

ed input.txt < script.txt

which is unintuitive, I believe. What if it was this?

edscript script.txt input.txt

I find this more logical—we run ed script upon the file.

I realize that ed is a forever stable project and some additional
features are likely not the focus, but I couldn't just ignore this
use-case biting me lately.

Best of luck,
