Make multi-line suggestions easier to use
Problem to solve
Multi-line suggestions https://gitlab.com/gitlab-org/gitlab-ce/issues/53310 are really useful and powerful, but hard to use. I need to manually adjust the range in the markdown field, but this requires some fiddling to get the right range.
Further details
This might be addressed by https://gitlab.com/gitlab-org/gitlab-ce/issues/4143 but this would probably lead to a situation where comments and suggestions share an identical range and become more tightly coupled. This would not be good if a conversation was started on a single line, and then someone else wanted to propose a fix to the single line comment by proposing a multi-line change.
Proposal
When a multi-line comment is made, the suggestion should automatically prefill to the range of the comment.
