I don't think it is git's job to police web server implementations,
especially considering that there is a gap between letter of RFC and
actual behavior. Anyway, it only runs the check for "*/info/refs" GET
request, which ends up in get_info_refs(). Other GET requests do not
check CONTENT_LENGTH. Also, the version of service which is started from
get_info_refs() do not consume input (I think, actually, the
"--stateless-rpc" argument is not needed there).

Yes, I'm working on it.
