No, the config file value stored for "Pretty Print" in 0.6 is what you used for "Pretty Print" in 0.6.1, rather than for the equivalent of "Pretty Print Tidy". I did mention this in an email ages ago, and in response I think you changed the default value for new users (with no sigil.ini) to be Pretty Print Tidy rather than changing the mapping of the config file value.
I have verified this btw, if you have both 0.6 and 0.6.1, start up 0.6, make sure it is set to "Pretty Print", exit and start 0.6.1 and it stays at "Pretty Print".
