Honestly I went with strncmp() over strcmp() on little more than a
hunch. I actually prefer strcmp() as looking cleaner, with one less
arg and no need to remember the existence fo the null at the end.
Maybe I'll change it.

As to the style of logic, strncmp() and strcmp() both return zero for
an exact match, a positive number if arg1 is lexicographically greater
than arg2, and a negative number if arg1 is less. This is not strictly
a boolean output, so my choice of !strncmp(...) is probably bad style
anywhere. I remember old assembly language too well.

How about this for style?
                   if(strcmp(".", field[7]) == 0 || strcmp("..",
field[7]) == 0)
                            return nil;
