Improved on "try_files" documentation: - documented that "root" and "alias" affect the path being checked; - provided an example of using a URI as the last argument; - documented that last argument can point to a named location.

While building nginx version 0.7.66, 0.8.35 or higher on Linux
the following warning messages are issued:

<programlisting>
warning: `sys_errlist' is deprecated;
    use `strerror' or `strerror_r' instead
warning: `sys_nerr' is deprecated;
    use `strerror' or `strerror_r' instead
</programlisting>

This is normal: nginx has to use the deprecated sys_errlist[] and sys_nerr
in signal handlers because strerror() and strerror_r() functions
are not Async-Signal-Safe.
