[Groff] Shouldn't troffrc-end use .do so it works with -C?

[T. Kurt Bond]

Shouldn't troffrc-end use .do for the ".if r ps4html" and 
".if !d HTML-"... lines so that troffrc-end works with -C (original
troff compatibility mode)?  

troffrc uses .do in similar situations.

If it doesn't every document typeset with -C gets the text

    ML-IMAGE-INLINE    .ds  HTML-IMAGE-INLINE  ML-IMAGE           .ds
    HTML-IMAGE ML-IMAGE-RIGHT    .ds  HTML-IMAGE-RIGHT  ML-IMAGE-LEFT
    .ds  HTML-IMAGE-LEFT  ML-IMAGE-END      .ds HTML-IMAGE-END ML-TAG
    .ds HTML-TAG ML-DO-IMAGE       .ds HTML-DO-IMAGE bogus

added to the beginning.
