Do you have a reference where we can read up on this "caret escaping"?
If it's context-dependent it seems like it would be impossible to decide
generally which to use, and we might need an extra option to choose
between both quoting forms (abusing the "quoting" option for this is
wrong because the difference in Windows is semantical while in Unix it
seems to be purely aesthetical).

I see zero usefulness in the "backwards compatibility" feature.  It just
doubles the size of the code with no advantage except "it may be more
readable in a few cases".  I think if this more readable version is
desirable to have (which I seriously doubt), it should be put in an egg.
