Not trivially. The difficulty is that the context from previous lines
might affect whether something should be transformed - e.g. we mustn't
transform a line that's inside a string. And we need to be careful
about things like this:

In [1]: 5 \
   ...: % 2
Out[1]: 1

Again, apologies that this API hasn't been better maintained.

Best wishes,
Thomas
