+# 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.
