I don't think this hurts to fix. rust-lang#2781, which surfaced this issue, has a number of comments relating to similar but slightly different issues (i.e. dropped comments in other places). I can mark rust-lang#2781 as closed and then will open new issues for the comments that are not already resolved or tracked. Closes rust-lang#2781

There was a problem hiding this comment.
Did you see if using combine_strs_with_missing_comments would be viable? Haven't had a chance to look at this too closely yet, but most cases of comments getting dropped between strings combined with format! can be resolved by using combine_strs_with_missing_comments
There was a problem hiding this comment.
Nice tip! Updated to use combine_strs_with_missing_comments.
