Show both original and updated diffs in discussions
Description
When creating a discussion on a code line in "changes" tab of a merge request the code is attached to that discussion. This is awesome but when you later want to check how the code has been updated you are forced to dig into the changes and look for it.
Proposal
Allow the user to see current / original diff of that part of code and / or jump to the full changes already positioned in the file / line.
Even better: allow the user to change / mark a new line in the updated merge for the modification so that when I the user is resolving a discussion he can correct the line of code interested.
