How do I reference a specific issue comment on github?
You can click on the date in the header of the comment to get a URL to the comment
For example, for issue https://github.com/centic9/jgit-cookbook/issues/5 one of the comments has the following link: https://github.com/centic9/jgit-cookbook/issues/5#issuecomment-51084491.
Since August 2018, there is a more intuitive (and likely more reliable) way.
See "Copy the URL of a comment":
Previously, in order to grab a permalink to a comment within an issue or pull request, you’d need to copy the URL from a comment’s timestamp.
Now you can click Copy URL within the comment’s options menu to quickly copy the URL to your clipboard.

This works on commits in a Pull Request too:
https://github.com/moby/moby/pull/37558#discussion_r211356672 refers to:
And since February 2019, that works on mobile too!
Issue and pull request comment permalinks can now be copied on mobile devices, via the comment action menu.
Simple method:
Every comment in github has header like below
[Commenter Name] commented on [x days ago]
Right click the date information i.e. [x days ago] and copy the link
