Hah--if I had just read all the way to the bottom of the message I'd cited, I would have found a working link to archives for all 4 (+1) editions of Plan 9. Good show on the Plan 9 Foundation. Thanks, humm--this is good enough information to enable me to further populate the "History" section of groff_char(7). In the past week I've also noted that nearly all of the special character identifiers that groff predefines and aren't already precedented in AT&T troff provide mappings for the PostScript Type 1 Symbol font. There are only a few stragglers, which I asked for help scooping up earlier this month.[1] I aim to follow up on that once I fix some build system problems.
