Here you are (in doing this, I noticed I had failed to update
man/groff.man ... additional patch attached for that):

2006-09-01      Nick Stoughton  <address@hidden>
        Add a request, '.pev' to print environment information 
        (similar to .pnr and .ptr to print number registers and traps).

        * src/roff/troff/env.h: add member function print_env to the
          environment object

        * src/roff/troff/env.cpp: (environment::print_env): New function
          to print a given environment state.
          (print_env) New global function to iterate through the
          environments, printing each one.

        * doc/groff.texinfo (Debugging), man/groff.man: Document .pev request
