The problem with that theory is that the current implementation doesn't actually
store line numbers in the filters in the PM. The filters are simply stored
as a sequential list. Line numbers are a figment of the CLI's imagination.
If you don't believe me, just try deleting lines 5, 7, and 9 from a filter
by typing:
set filter blah 5
set filter blah 7
set filter blah 9
You'll find that you actually delete 5, 8, and 11.
