To be fair, that's a red herring in an age where most languages have tools available to clean up and reformat a weirdly formatted file directly in your editor. (I have Perl::Tidy bound to Ctrl+E and that combination gets hit more often than the space key, especially on code i am writing.)
Reformatting also breaks line numbers which makes it difficult to talk about the code with others.
Ctrl+C and Ctrl+V are a thing. The last time i looked at code on paper was years ago. In practice over the past 9 years i have not looked at any piece of code that i wasn't able to tidy so i could work with it.

Ctrl+Z is also a thing, as is a vast number of pastebins. Again, in practice i have never run into the problem you describe, and i work with what is claimed by some to be the most unreadable mainstream language in existence.
