I compared the output from the earlier ones with this one; the way
the displayed sample was shown in the previous rounds looked better,
at least in HTML pages.  The earlier ones used "listingblock" in
which the sample is contained in a <pre>formatted <code> block, but
this one ends up in a series of one-<div>-per-paragraph.

-	if (transform_stdin) {
-		char buffer[2048];
+	if (annotate_stdin) {
+		struct strbuf sb = STRBUF_INIT;

This will break the compilation at this step.
