Another prime example on the typical arrogance of this trade, of computer scientists:

My brain immediately goes like: You nitwit, base64 comes back from E-Mails, where you would work with Mail-Server's conception that your mails were all written, legible characters. Of course you should expect newlines, potentially whitespaces and tabs in it.

But that would be stupid of me. There's so much old knowledge and know-how we carry along for many decades - around 50 years in case of mail and SMTP. Unix and Linux are a specially egregious example, with so many conventions.... just ran into a long standing bug a few days ago, with some GECOS implementation (that's 62 years old stuff). We do a lot of good in throwing out the now unnecessary old stuff and separating the wheat from the chaff. Again and again.

In so far: Thanks for the pointer on that Base64 appears strange (also please do not let us talk about groff).
