htons et al. works on explicit 16- and 32-bit quantities and not the

machine dependent "short" and "long" integer.  Correct and enhance manpage.
Change all short and longs to u_int16_t and u_int32_t, respectively.

 .Sh DESCRIPTION
 These routines convert 16 and 32 bit quantities between network
-byte order and host byte order.
+byte order and host byte order.  The last letter (s/l) is a mnemonic
+for the traditional names for such quantities, short and long,
+respectively.  Today, the C concept of "short"/"long" integers
+need not coincide with this traditional misunderstanding.
 On machines which have a byte order which is the same as the network
 order, routines are defined as null macros.
