I have tried the following. Concerning defaults and preserving old
choices, it does what it was made for. However, there's one problem I
don't understand: The hyphen question is always shown twice. The second
time seems to be just before postinst is started, or at its very
beginning. 

It even doesn't matter whether I use the line

db_fset tetex-bin/hyphen seen true

or not. I have inserted 

db_fget tetex-bin/hyphen seen
echo "After set $RET" >> /tmp/seen

at different places, and the outcome is that the question is flagged
seen, even without explicitly setting this, after it has been
displayed. Could this be an artifact of my pbuilder environment?

Thanks, Frank
