portupgrade modifys EVERY +CONTENTS now?

[Tuc at T-B-O-H.NET]

Hi,

	I've noticed that recent version(s?) of portupgrade seem to update
the +CONTENTS of *EVERY* package on my system, not just the ones it used to
actually make a difference to. Is there a way to revert to the old behaviour?
With 915 ports (WAS only around 600 before the recent Xorg upgrade) its a
killer. On my Soekris with a CF drive, and only 57 ports, its still killing
that CF chip.

		Thanks, Tuc
