That was intended, and this patch is basically just a copy of the
loadable version.  I don't really find it necessary to make the builtin
sleep a complete copy of the external one.  The code would significantly
increase if we add a parser for those formats.  Also it's basically
people's fault for not reading documentation.  One should be aware
enough if they enable the builtin.  Mksh's sleep also does the same.

Anyway I respect whatever Chet decides it to become.
