To add more data to this discussion, I've been playing with the GitHub Issues API recently, which pretty-prints by default. I grabbed the last hundred open issues from the Mozilla Persona repo, and found

        == Uncompressed ==
  Pretty Printed: 312,556 bytes
        Minified: 272,604 bytes
                  -------------
           Delta:  39,952 bytes (+14.66%)
Not as bad as a 24% hit, but that's all moot because gfodor very explicitly discussed using gzip when pretty-printing. Let's see what happens there:

           == Gzipped ==
  Pretty Printed:  41,748 bytes
        Minified:  40,648 bytes
                  -------------
           Delta:    1,100 bytes (+2.71%)
Not as good as the original claim of <1%, but still pretty darn negligible.

Thanks. My <1% claim was ill-founded, I was assuming the use of tabs and trailing braces to minimize single-character lines so a little arithmetic in my head pointed to a small relative cost. But out of the box pretty printing does not try to minimize whitespace characters like this. Seems like it could be a worthy hack.
