x.py: setup: Refactor to centralise list of profiles

Put all()'s otuput in the order we want to print things in, and add a
comment about why they are in this order.  Provide purpose() and
all_for_help().  Use these things everywhere.

Move all the abbrev character ("a", "b", etc.) processing into
interactive_path.

No functional change.
