That's a good question. I don't see a real reason for it beside that
it is this way since 2001 - before there was no parent-walk.

I haven't tested it, but as a workaround it should be possible to
set Dir::Aptitude="."; so that paths like /srv/sid/./var/lib/aptitude
are returned by current FindFile implementation.
