    [troff]: Boolify env.cpp (11/25).
    
    [troff]: Boolify more `environment` class member variables, member
    function parameters, and local variables.
    
    * src/roff/troff/env.cpp (environment::choose_breakpoint): Demote local
      variable `best_bp_fits` from `int` to `bool`.  Assign Boolean literals
      to it.
