Advanced features when including files

[jcelerier]

Problem

Hello,
I have some documentation with mdbook which heavily reference material under the form of source files, which I include for instance like this :

```
{{ #include some/file }}
```

Now I would like to globally control how this pattern is rendered, for instance automatically display a link to the source file in the git repository for easy access. What would be the best way to do this ? Most likely this cannot be done in the theme as by then the content has already been copied.

Proposed Solution

What would solve my immediate problem: an option in [output.html] such as display-include-file-links = true which would render a small bar above each code block with a link to the included file. The host could be provided in another option, e.g. for instance to point to source files hosted on github in the source repository.
