Jarno, you could add vi an option that applies headlessly a key sequence
from a file? For example, a regression test with it would catch this
first line deletion error that I have now. Pretending the option exists:

printf '\nseitan\n' >seitan; printf 'dd\n:wq!\n' >key
vi -s key seitan; cat seitan
# Want: seitan\n
# Have: Segmentation fault

I don't install either more or less, and will be glad to not need either
vim or a lynx wrapper, if you teach toy vi stdin. Other tools should
just pipe to it. It's a case where reuse of entire command makes more
sense than sharing a library function.
