Here comes v2.

 $ src/sleep -- -inf inf
  src/sleep: invalid total sleep time -nan
  Try 'src/sleep --help' for more information.

I added some more test cases for invalid combinations
with nan, -nan and -inf, and avoided multiple diagnostic
messages in the case a single argument already was
considered !ok like in 'sleep -- abc -inf'.

Finally, there was a stray "Conflicts: NEWS" in the commit
message of v1, sorry for that.

Any comments about the possible timeout races?
(I didn't get failures here, even with high load and
'make check -j'.)

Thanks & have a nice day,
Berny
