I'd love to see stats on that, Guido.  I'm sure it's true in your
immediate vicinity, given what you work on, but I don't believe it's
true in general.  And even for "text" files, it begs the several
questions of the expression of the text in a file, which is always a
binary artifact, due to the fact that files store bytes, not "text".

I'll shut up now...
