Since nobody expressed affirmation nor disaffirmation so far, I'm faced
with the following possibilities:
a) Don't add the Pre-Depends and wait for someone to whine that his
system broke because libncurses5 was unpacked before libtinfo5.
b) Add the Pre-Depends and wait for someone to whine that no consensus
on debian-devel was reached according to Policy ยง3.5.
I'm inclined to go with b), so if anybody has objections, please raise
them soon.
Cheers,
Sven
