You are the only person with the fortitude to go near that code lately,
so all I can say is 'please document the new regime' ;-)
Well, the new functions are documented in the mh-format man page, and I
even put in the bits about repl's duplicate supression for formataddr
since that was news to me!
More seriously, whatever else you discovered as you got there is worth
documenting as well. It's certainly one of the least understood bits of
the code base ...
Maybe I'll add some comments to fmt_compile.c and fmt_scan.c. It's not
_terrible_ (other than that code being horribly non-reentrant, but I
guess that didn't matter too much back then). Also the memory management
is pretty much non-existent as well (I guess for single-shot commands,
it again wasn't a big deal). But once I got into the middle of it
you could follow it reasonably well. And I will note that Oliver Kiddle,
Josh Bressers, Peter Maydell, and Jeffrey Honig have all been inside of
that code, so if I get hit by a truck there is still hope for nmh! :-)
