fix comment used in PIC files by plugin back end

The PIC plugin seems to have copied some details from the core PIC
implementation (lib/common/picgen.c) without noticing that the core
implementation juggles its comment format to emit PIC comments on pages and only
use TROFF comments at the top level. Related to #131.
