Well, this is doing two different things.  When os.name is 'nt', you
are getting rid of all *trailing* CRLFs.  Otherwise, you are getting
rid of all LFs *anywhere in the string*.  (Even if it so happens sauce
will only ever have LFs at the end, it's still better to use the
method that is closest to your intended meaning.)

Personally, I prefer using sauce.rstrip() with no parameters (one of
the suggestions Rhodri mentioned) if it's not important to preserve
trailing spaces, since this will work regardless of end-of-line style
(and typically, trailing spaces, tabs, etc. are undesirable anyway).
