There seem to be (at least) two ways to implement this.  When the user
specifies ".pl -1", the code can either:

1. Store -1 as the page length.
2. Set a new flag that indicates page-length handling is to be disregarded. 
Any code that compares against page length is made conditional on this flag
being unset.

In many cases, implementation 1 may automatically do what's desired without
further code change.  But this raises your concern about interaction with
negative vertical drawing positions.

Implementation 2 is a more invasive change.  But because it skips page-length
checking altogether, it avoids the prior concern.
