<nitpick> This is a doc. bug! ~v is mentioned in mail7.nr in the same fc8c50acc0 "commit". This has April 19, 1979 date. The same as the 2bsd date on TUHS unix-archives. See my previous message. ~v was already in! > By the time of BSD-1-54-ge684660a6a2, src/Mail/Mail.help.~ lists both. > https://github.com/dspinellis/unix-history-repo/blob/e684660a6a291c1e4672912bc1b80ffb00934623/src/Mail/Mail.help.%7E > > So although the released code had both, I think it's likely that `~e' > was there on its own, and then `~v' added as ex's vi mode came along. > I also noticed that Mail's string option was at one point `EDITOR' for one > and `VISEDITOR' for the other; also suggestive that one came first > rather than both together. This is in mail7.nr but looking at the sources, it is 'VISUAL' so I suspect this is another doc. bug (both bugs are also in doc/Mail/mail{3,7}.nr in the 2bsd dist. on TUHS). </nitpick> :-) -- nmh-workers https://lists.nongnu.org/mailman/listinfo/nmh-workers
