[PATCH 1 of 1] Avoid insertion/deletion of CRs on stdio during hgserve

[Maquelin, Olivier]

Please disregard the previous patch and use the following instead. The
calls to set_binary() lacked a 'util.' in front of them (not sure how I
managed to miss that). Also, as was pointed out to me, it is better to
have the import of msvcrt fail outright (i.e. not have it in a
try/except block) instead of 'hg serve' failing in strange ways.

Sorry for the confusion.
