If libedit really is a complete replacement for readline (they  
provide the same functionality and at least compatible symlinks) then  
it should be a virtual. Currently the libedit ebuild doesn't install  
any compatibility symlinks or the headers, which means that on Gentoo  
they aren't really virtuals at the moment.

Making them a virtual is probably a subject for broader discussion  
(making libedit install readline compatibility, make libedit/readline  
block and make them provide="virtual/readline").

(Because I don't know how this would be done) - where/how would we  
add readline.h to /usr/include?

Well making libedit/readline virtuals (if they really are) isn't  
dirty at all - it'd be the right solution. Not so sure about moving  
readline.h around...
