Link github wiki to trunk code
github
Solution
The wiki markdown-cheatsheet does show a link to a source file (in a wiki page).
You can use a simple http link, which means you can reference any file, with line number directly in that url.
[text](https://github.com/adam-p/markdown-here/blob/master/utils/i18n.js#L11-L12)
Or you can use a relative path
[I'm a relative reference to a repository file](../blob/master/LICENSE)
But in that last case, the line numbers might not work.
Problem
In an Github wiki it is possible to embed code. Is it possible to link to source code via a filename (and line number?) from within the wiki's repo? Ideally there would also be some type of error displayed if the referenced file was later deleted. I looked at these issues, but they do not cover it: Linking to other Wiki pages on GitHub?
