It sounds reasonable to not allow PR comments in review comments on individual lines, yes. As Erik says, they are presented differently, can be hidden, and form a "different kind" of communication.

I still think the main review "comment" (or whatever to call it) deserves to be parsed for PR comments. Once it is posted, it looks just like a regular comment. If it were not for Skara treating this differently, I would have had no idea it was even treated differently internally in Github. To me, it is like a "approve this PR + also add this comment", not "approve this PR with this special kind of comment that can only be generated here but looks like any other normal comment".

David:
> Even in the main review comment what gets scanned - all the text? Only the start of lines? I would worry about text being misconstrued as a command. This would especially be true for skara PRs where review comments may well refer to PR commands as part of the discussion.

I am not sure what you mean by that? My example is the kind of comment I've been doing far too many times before remembering that it will not work, I look at a change, check the build changes, presses the green button, selects "Approve" and writes:

This looks good from a build perspective, but you'll need someone from core-libs to check it as well.

*LOL* 

Thank you @openjdk bot for providing a quick example that the risk for "misconstruing" commands are just as present in normal commands, and not something that will be a special problems for main review comments. :-D
