The problem was that I didn't want to blow away peoples' playlists.

I couldn't see how to do that without:
	1) using a scripting language (which you've objected to)
	2) putting the upgrade inline
	3) writing an upgrade tool

Do you have a better method?

Note that we're not exactly supporting multiple versions; we only save
in the new schema.

Apologies; I have vim setup to indicate tabs versus spaces, but I must have
missed a few of the original lines in the file.  Again, indent.pro would
have solved this problem.  I will craft my own.  Will you accept it as a
patch? ;-)

Point taken.

In this case, the broader goal here was to add greater functionality to the
playlist code.  The schema update is part of that, so even if you can't
abide by the efficiency concerns, please accept the attempt to improve the
featureset.
