This is fine, the last two parameters here are the previous and current
version of the installed package.

I've tested that with `dpkg -D2' and it seems to pass the right
parameter:

`----
I've put a few lines with 'echo "$1"' into the lprng preinst, and it
seems that $1 gets lost after the call to check_configfile_locations;
since that function does not do anything obviously wrong to reset the
positional parameters, it seems debconf does something fishy here.
Reassigning to debconf,
Sven
