When we open a SVN page like this
we are able to add #l___ to the url to create links pointing to a specific part of the code.
On [[MediaWiki:Common.js]] and other [[*.js]] and [[*.css]] pages, there is no way to do this at the momment.
It would be great to have such a feature, mainly for long script pages.
Similarly, it would probably be desirable to display such line numbers in those js and css pages.
