We currently format extension eval URLs scripts with this template: `debugger eval called from ${evalCalledFrom} - eval code` it would be nice to switch to a more compact URL template: `${callerInfo.url}${lineInfo}/debugger-eval`. The benefit would be that the new debugger client would have an easier time showing the debuggee script tab and processing the URL in general. Here's a first pass at a patch: https://gist.github.com/jasonLaster/34996ed26c0b10f002f02569aa21614b it is missing the other cases where "debugger eval" was usesd.
