I just started using el-get and while trying to migrate my config to it I found multi-web-mode was outdated. Later on I checked and the recipe used to grab it points to an outdated fork. As the author I'll recommend updating the :pkgname to "fgallina/multi-web-mode" since I'm actively maintaining it.
Do you want to send us a pull request so that your name is on the git author list?
There we go, it opened other ticket in the process, this is the first time I use pull requests so I don't know if that was expected.
Thanks for having done so, merged :)
