Agreed. I prefer the second patch too, which I'm reattaching since it
was mangled (whitespaces; 'patch -l' is not enough, but 'got patch'
managed to apply it.)
Will wait a bit still in case someone disagrees, but I don't really
see the point in having hack scraping $PATH for finding itself; the
format wasn't changed since the initial import so I guess we'll be
fine :-)
