Speaking for haproxy, the second one will work, because it splits header
values on the commas and trims the spaces. So the first above will be
considered as an empty expectation followed by a 100-continue (but haproxy
only considers the first Expect value) and the second one is OK.

Haproxy's processing of Expect is incomplete and almost unused, so it
should not be seen as a reference implementation at all (!). However
the semi-colon after 100-continue was not supposed to happen in 2616,
which is why I think other implementations might get trapped.
