I can't reproduce what you're saying about hyphens vs. minus signs with regard to cutting and pasting to the command line. I use acrobat reader to view a PDF version of your document. When I copy your first example to the command line, my acrobat translates the minus signs (internally coded as "AD") to spaces. In your second example, the hyphens (coded as "2D") retain their encoding as "2D" (hyphen/minus in ASCII) and are thus copied correctly to the command line. (But of course the minus signs look much better (with regard to "looking like a command line") in the printed document, in particular when using non-typewriter fonts such as Times.) "Zollzeichen sind keine Anführungsstriche." The thingies you're referring to as "Zollzeichen" are "typewriter quotes", not "Zollzeichen" (inch marks). The glyphs used to properly denote inches (feet, seconds, minutes) are "primes", not typewriter quotes. (Even Adobe gets this wrong (www.adobe.com/education/pdf/type_primer.pdf), and they should know better, being a company that practically grew up on computer typography.) Primes are (usually) a bit longer and slightly slanted. Typewriter quotes should never be used in typography except in the context of emulating typewriters (and on teletype-like devices with a limited character repertoire). "Die beiden letztgenannten Zeichen werden im troff Modus ignoriert." No, they're ignored in *nroff* mode, i.e., on devices which can't reasonably display them. (Additionally, german grammar requires a hyphen in compound nouns, so it should be "Die beiden letztgenannten Zeichen werden im nroff-Modus ignoriert.")
