[Monotone-debian] Patch: do not blindly delete /var/lib/monotone on purge

[Ludovic Brenta]

Because the directory may contain other databases.  I just lost all of
my databases :/ luckily, monotone being distributed, I could restore
them quickly.  Still I'll have to fetch a couple of private databases
from backup.

Zack, looking at net.venge.monotone, I don't see how you create your
packages; the latest revision of the debian/ subdirectory also
contains source files much later than 0.35.  How do you do it?  Have
you got a private database for the debian scripts?  I would have
expected n.v.m to have several heads, one of which a direct descendent
of t:monotone-0.35, with only changes to the Debian scripts.

I'm ready to upload with the patch below.  Any objections?  Otherwise,
please apply it for future uploads.
