I am not 100% convinced that this is a good idea. If somebody wants to
setup a "proper" web server running aurweb, this workaround makes it
harder to figure out what went wrong if PATH_INFO is unset due to some
misconfiguration. On the other hand, being able to run a quick test
using `php -S` is quite nice. Would you might adding a notice to the
commit message that this is specifically for `php -S`?

I also think that a note on how to test aurweb patches with `php -S`
should be added to the documentation. Maybe in INSTALL, before the
"real" setup instructions? Something like:

    For testing aurweb patches before submission, you can use [...]

    Note that you can only do limited testing using the PHP built-in web
    server. In particular, the SSH/Git interface will be unusable. For a
    detailed description on how to setup a full aurweb server, read the
    instructions below.
