Actually, I did a hack that does that too (this one is nicer, though). I can’t find mine offhand (too many makefiles), but it is also a Makefile target that runs grep -B1 on the Makefile itself and spits out each target’s name and the comment I usually add to it… And my Makefile template uses .env files too… I think I cover most of the list in my day-to-day use.
