+I thought that, as internal pages, comments were not preprocessed
+(and so their date attributes did not have a chance to take effect) until
+they were already being inlined, by which time they have already been
+sorted by the files' ctimes. Actually, I was wrong about that - internal
+pages have a special case elsewhere - but they did skip the `scan` hook,
+which is also fixed in my branch.
+
+The real bug was that the preprocess hook for comments didn't run
+in the scan phase; my branch fixes that, streamlines that hook a bit
+when run in the scan phase (so it doesn't htmlize, and only runs nested
+directives in scan mode), and adds a regression test. --[[smcv]]
