"View file on fork" link in file view

[Jackenmen]

E.g. file view page, like:
https://github.com/sindresorhus/refined-github/blob/master/source/options.html
would have a "View file on fork" link (button) which would redirect you to the file on your fork, i.e. for me it would be (assuming I would have a fork of this repo):
https://github.com/jack1142/refined-github/blob/master/source/options.html
If user doesn't have the fork yet, either the button should not be available or it should also create the fork for the user.

PR welcome :)

Back to this topic: I think this feature can be part of forked-to

The forks we list could point to the same view (in this case, the same file) instead of opening the fork’s homepage.

We already have this behavior for links under the More menu, where compare for example isn’t a mere link to the Compare page but also uses the current branch, if any.

Food for thought.

I was thinking about this. We dont know what branch to open the file on. I think the best way to do this is by copying how comments-time-machine-links works and ask the user if they would like to open the file they were just using.

We dont know what branch to open the file on.

HEAD

I think we should just alter the existing link if isSingleFile or isRepoTree.

For example, on this page:

// https://github.com/yakov116/refined-github/tree/123/media

The "forked from sindresorhus/refined-github" link:

Should point to:

// https://github.com/sindresorhus/refined-github/tree/HEAD/media

Brilliant and simple idea

The same concept can be applied to forked-to, in the other direction, which is actually what this issue is about.
