Yeah, I rewrote the patch and email a couple of times as a direct result
of this issue and it's why I settled on the "ignore the leading slash if
present" solution.  I don't know of an environment that never sets
PATH_INFO and just uses SCRIPT_NAME (I'm pretty sure that violates the
CGI "spec" pretty aggregiously). In every environment I've used
SCRIPT_NAME is set as the part of the path that triggered the invocation
of the script and PATH_INFO is everything after that. There are some
situations where this holds but figuring out the real quixote root
requires a lot of work (mod_python and Apache Directory directives, for
example -- don't do that).

Thinking about it more, I'm pretty sure Apache, when PATH_INFO is
present, always starts it with a '/', however.
