Subject: Renumber the test scripts into themed ranges

    t000x  the ground the suite stands on: git version, html validity,
           the cache
    t01xx  page content, one script per page
    t02xx  features that cut across pages: filters, submodule links,
           dates, limits
    t03xx  defence, the security regressions and the $HOME promise
    t04xx  the helper tools under tools/

+# The patch page serves a commit as a mail ready patch, so that a change read
+# from cgit can be fed straight to git am. The checks compare that output
+# against git format-patch for a single commit and for a range of them, once
+# the CGI headers have been stripped, which means the two have to agree line
+# for line. The last one sets max-patch-count so a range wider than the limit
+# comes back cut short.
