[Pkg-mailman-hackers] Bug#358575: Purging mailman safely

[Roger Lynn]

Would replacing (please excuse the line wrap):

  for file in $(sed -e ':/etc/mailman:!d' -e 's:^[0-9a-f]* *::'
/var/lib/ucf/hashfile); do

with

  for file in $(sed -e '\|^[0-9a-fA-F]\+[[:space:]]\+/etc/mailman/|!d' -e
's|^[0-9a-fA-F]\+[[:space:]]\+||' /var/lib/ucf/hashfile); do

in /var/lib/dpkg/info/mailman.postrm (is this the right file?) allow me to
safely purge 2.1.7-1 without having to compile and install 2.1.8-1 first? I
assume the same would apply to Sarge users.

Thanks,

Roger
