Git commit
commit 5e231d1d9cb90471344f0fff80f3cea0a57e718b
Author: Guy Harris <guy@alum.mit.edu>
Date:   Sat Sep 20 15:51:10 2014 -0700

    Fix wslua_filehandler_open() to work as wiretap open routines should.

    They should return 1 on success, -1 on error, and 0 if there was no
    error but the file isn't one of the type for the routine.  They must not
    return any other value.  If they return -1, they must set *err.
