    Fix buffer overrun in gp_enumerate_files_next.
    
    If pattern="*" and patlength = 1, then pathead = 1.
    
    When we look for any following subdirectory, the code attempts
    to look for the next subdirectory name. To do this it starts
    searching from the byte after the position of the current '/'.
    Unfortunately, if the string ends at the current wildcard, we
    don't have a '/', we have a NUL terminator. This means the
    current code starts looking just after that.
    
    In code terms this means the current code accesses at
    pattern + pathead + 1, without checking pattern[patthead] first.
    This is a simple fix.
    
    We also take this opportunity to simplify a couple of while loop
    conditions. The extra negation is too much for my tiny brain to
    cope with.
