Copying GitHub link to a file?

Can we have a simple function that, when right-clicking on an indexed, unmodified file, and we are on a branch tracking a GitHub branch, provide a choice to copy a link to the corresponding GitHub file?

It copies a link like https://github.com/<account>/<repo>/blob/<blobid>/<filepath>#L<linenumber> or

https://github.com/<account>/<repo>/blob/<branch>/<filepath>#L<linenumber>

Just like this (in Resharper): 

I believe this would be a useful addition to the current feature set.
