Comment(by edsko):

 Trac gave a "database locked" error when I uploaded B.hs; when I tried
 uploading it again, it added "B.2.hs" and then "B.3.hs", even though it's
 not showing "B.hs" as being uploaded -- nor can I remove any of these
 files. Sigh. Please rename "B.2.hs" to "B.hs" before running the test.
