to my knowledge no troff version before the C
rewrite in v7
Apologies if I missed something, but between this list and COFF there's so
much low S/N traffic I skip a lot of it. Having said that, was there ever a
troff in assembler? I'd always had the impression that the first one was in C.
So that one is a "troff version before the C
rewrite in .. v7", but it is in
C. Is that of any interest?
Without having looked into it more than you have it looks like it is
just an earlier version of the C code, but what I'm after is the
original assembly.
