Re: sys::open-url doesn't check $PATH

Hei Leif.

    L> try (setf (HQN-WEB::DB-BROWSER-LOCATION) "/usr/local/bin/")

Thanks for this suggestion, but this seems more like a hack.

I'm making software for others to run, so would prefer open-url to do
what it says in its docs, to check for browser candidates in the users
PATH environment variable.

Cheers,

-anders

Right, that did the job for me locally.  Thanks.
