base85: avoid a spurious use-before-initialized warning in `pure` module

The error wasn't possible because the only way for `acc` to not be initialized
was if `len(text) == 0`.  But then `0 % 5 == 0`, so no attempt at padding was
done.  It's a simple enough fix to not have PyCharm flag this though.  The value
needs to be reset on each loop iteration, so it's a line copy, not a line move.
