Don't link to line numbers in GitHub
ProTip: Hit the y key on any GitHub page with source code.It'll instantly expand the URL to its canonical form, e.g.https://github.com/sass/libsass/blob/master/parser.cpp#L29-L...tohttps://github.com/sass/libsass/blob/fca1f75a14fe5336c7b1a4b...which stays valid indefinitely (unless the commit is deleted from the repo).P.S. Hit the ? key for more keyboard awesomeness. :)
