A single line while "example.com example.net" will request a single certificate
Even though the meaning looks to me clear, shouldn't the word while be replaced?
Yes, that looks like a clear typo for "file" (camouflaged by the fact that the sentence might plausibly have been connected to the previous one with a "while" or "whereas").
I've looked through for anything else to moan about while I'm here, but there isn't much.
the previous line has "Dehydrated" where I expected "dehydrated". (In fact I expected it to be highlighted throughout, but never mind that.)
the definition of --force mode has:
Force renew of certificate even if it is longer valid than value in RENEW_DAYS
This isn't quite idiomatic. If I'm correctly guessing what
"--force" does (implying this isn't very urgent) I would suggest:
Force certificate renewal even if it is not due to expire within RENEW_DAYS
