KSW found that some edited files from 1851 were further along in their editing process (addition of markup and pagebreak tags) than the ones in SVN, so we had to replace the SVN copies with the older ones; I then had to re-run the automated abbreviation markup regexps I'd (thankfully) documented carefully on the blog. We also found one file which had the wrong reference info (it was marked as CO 305 03 when it's actually in the War Office records), and another file which was a duplicate of the following file. All fixed.
