different link color for internal/external links

[jdtsmith]

Just discovered this brilliant package and project. I hesitate to follow links that will open a browser, especially in full-screen Emacs. I wonder if it would be simple to style external vs. internal links distinctly?

Interesting idea, I'll investigate if shr allows this. It likely does. (FWIW, the link target is displayed in the echo area.)
