I find it helps to think of it as subtraction.  i.e. strcmp(s1, s2) <=>
(s1 - s2).  This also helps keep straight the meaning of the sign of the
result (which one is greater), in the rare instances where one cares.

I personally prefer to write `if (strcmp(s1, s2) == 0) ...' instead of
`if (!strcmp(s1, s2))' for this reason, since it helps me think of
strcmp as an arithmetic rather than logical operation.  Even though it
is a few more bytes.
