Out of sight out of mind

[Byron Heads via Digitalmars-d]

Does github link issues with pull requests (and the conversation) and 
commits?  Does it link issues with sub issues/tasks?  Can Issues link to 
other repos (link issues that are in both runtime and std lib)?  If it 
does have these features (and they are easy to use) then I would back it.

I have found jira to be one of the best trackers out there.
