Won't that increase the confusion, which is IMHO already too high,
between codepage.el and code-pages.el?  The cpXXX encodings you listed
above are for DOS only, so it is okay to call them cp*.

That's because DOS never pretended to be a net-connected platform, so
it was unimportant to say what encoding you worked in, since your
machine was stand-alone anyway.
