Except, well, it does. At least if you've also changed the conffile in
the package (perhaps in a later upload than the one where you moved the
conffile, if people didn't upgrade to the version in the middle). The
same (mis)behaviour happens if you make a non-conffile a conffile and
then change it in the package; I can produce a trivial test case if you
like. This is a problem with both groff and man-db, despite my
maintainer scripts doing (as far as I can tell) the right thing.
It's not clear to me whether it's a (fixable) bug in dpkg, though. At
least in the non-conffile to conffile case it doesn't seem to have the
md5sums around at the right time. On the other hand, I don't know how I
can work around it in my packages, because the only thing that runs
before conffile replacement is the preinst and I don't have the unpacked
files handy at that point to do additional replacement logic myself.
