Starting from "Combined Table of Contents" in Doug McIlroy's
"A Research UNIX Reader" a table of which edition manuals appeared in.
Checked against manuals from bitsavers/TUHS and source from TUHS where
available.

Ingo points out there are cases where something is included but not
documented until a later release.

spell command from 4.4BSD, now freed by Caldera.
I have made some significant changes:
o spell no longer uses hashed files. The algorithm for generating
the hashed files breaks down for large files. Instead, I use the
same approach as look(1) and do binary searches of mmap(2)ed files
which has acceptable performance. A side effect of this is that
spell can now search multiple word lists.
o The spell binary has been renamed to "spellprog" so as to not conflict
with the spell shell script. This is consistent with other operating
systems.
o The putsuf() and putword() functions have been renamed to
trypref() and tryword() respectively for consistency with modern
versions and for general sanity.
o the spell front-end shell script has been completely rewritten
o The code has been ANSIfied and re-style(9)d

spell currently must be compiled with -fwriteable-strings to make
the -b option work. This should be fixed.
