↳ In-reply-to » OK time to put this to the test, I ended up setting my $VISUAL env {-here-} variable, so that jenny can launch neovim instead of plain old vi like {-here-} it is instructed in the code. But as you can see, I still get these {-here-} wired new lines every ~70th character (marked them with {-here-})

I might have found the actual source of my problem.

Jenny uses an .eml file when composing a twt …
and vim kinda auto formats it and inserts in those line breaks every ~70 character.

Then, I stumbled upon this link where Where someone reports that saving a .eml into a .txt might… corrupt the data?
