I've found an interesting contradiction and was wondering what behavior
sleep should have.  It checks for a command line flag with getopt(3) and
exits with usage() if it finds one.  However, it then checks for a '-' or
'+' sign.  If negative, it behaves like "sleep 0" and exits
immediately.  This case can almost never be triggered since the
getopt(3) will catch the minus sign, even if a digit follows it.

Current behavior:
sleep 0 = exits immediately
sleep -1 = exits with usage()
sleep -f = exits with usage()
sleep "   -1" = exits immediately and is the only way I know to trigger
the negative case.

What is the standard, desired behavior?
