c90r03 was removed from comment-tracking but the anchor was never removed. Its content was:
p090r3 | c090r_03 | x | x | x | NJR | Blank space left between the previous entry and this one may give clues to authorial intent and composition of the text. | tc, tcn, tl -- | -- | -- | -- | -- | -- | -- | --
We should either put it back in, remove the anchors, or change the anchors to a comment with similar content (which I vaguely remember to be what we decided)
replaced with anchor c158r01
