TECO-11 was, but it had didplay features. We had a screen oriented editor written in TECO that I hacked on. But it has .TES files that was TECO written with comments and whitespace. Those comment and whitespace where removed with MUNGE. There is some connection to make (which make have been part of it). There was a 60s joke burried in 'make love' where it would print 'not war' that I added to FreeBSD make for a number of years.

The TECO-11 macros like this were nothing at all like EMACS. And IIIRC, many of the TOPS20 Emacs macros had migrated to assembler, at least that's what I recall seeing when I used the display macro source feature back in school. Many were still in teco and made my head spin.
