+       pmccabe2html: escaping of special characters
+       Escape all '<', '>', and '&' in HTML output.
+       * build-aux/pmccabe2html (html_fnc): Call gsub()
+       instead of sub() to capture all '<', '>', and '&'.
+       Neither of '<' and '>' is special in a regexp,
+       so first arguments to gsub() are corrected. Also,
+       in replacement strings, ampersand must be escaped.
+       Finally, '&' must be handled first, then '<' and '>'.
