allow adding comments on lines outside of the changed context
Description
It is possible to attach a comment to a line of code (e.g. via a merge request), but only to lines near a line that is changed (e.g. 3 lines above or below lines added/changed/removed).
Proposal
Allow to add comments to other lines of code. For example, when a feature-branch updates all methods of some type, then if one method of such type is forgotten, then I would like to point this out by a comment on the line of that method. Because that method is not part of the change it is currently not possible to add a comment to that line.
