stop using readline.h

At least mention that it's required or even better vendor it.

I would not recommend vendoring a common library like readline; it should be available in any distribution and if edbrowse is packaged in such a distribution the packagers would want to use their readline, not a potentially out of date bundled version.

But mentioning all requirements in the documentation is a good idea, and making the use of readline optional is a reasonable request.

I don't know what this means. Sorry I'm not a packager. Do we "vendor" readline? It's just a library we link to, like libc or libm or libpcre2 etc. Karl Dahlke

"vendoring" would mean including all readline sources inside the edbrowse repository and building it together with edbrowse.
We do not do that (and there shouldn't be any reason to ever do that), just mentioning it as a requirement in the README should be good enough.
