Link to / Reference an issue comment in a commit message
Release notes
Problem to solve
Issues can often get lengthy when there are multiple contributors. One commit might fix something discussed in a single comment on the issue tracker, and it would be nice to track specifically what it references.
Intended users
Developers / anyone making commits based on issues
User experience goal
A commit should be able to link to an issue, or a specific part of an issue such as a comment. The user should be able to put some sort of information in the commit message to link that commit to a specific comment on an issue.
Proposal
Allow a commit message like like Fix discussed in #123@456 to reference issue 123's comment 456, showing the commit hash under this comment.
Further details
Something like this would be useful for when a specific comment contains information relevant to the commit - perhaps a screenshot, a list of options to help resolve the issue, a bug that is part of the issue's implementation, etc. Adding this feature would allow such comments to be addressed more specifically than the #12 link to the whole issue.
Permissions and Security
Permission to commit is all that is needed.
