Well, that fix does not break any tests.  Anything asking for
#contents that only needs #upToEnd deserves to break.

I'll commit this to trunk soon.

Right now using upToEnd is the 'problem' so a quick test would be to just 'self position: 0' before the upToEnd. The converter fudging after the read will return the position to whatever it was at the beginning, so that is all covered.
