Super!

Yeah, there are a lot of places where "goofy" (old-skool?) stuff like 
this happens, e.g., strip_bg_char. Yick.

Those look okay to me.

The only thing "wrong" that I found was missing comment on the new 
output_command_const; just to be maintainer-pedantic (even though I am 
not a maintainer). :-P

I say, commit it!

When I'm done rebasing my current work, I'll see if I can dig up the 
rest of my patches on this subject.
