Those apply to the parts the FSF wrote, certainly. For example, I
would frame that sentence with "Some parts are Copyright 1902-1954
FSF. About those parts, the FSF says:"

The same thing that happens whenever a bunch of compatibly-licensed
programs are combined: a really big copyright file.

You're right that it's probably better not to change the text, but
simply to set context appropriately. The term "This program," for
example, has a very specific referrant -- it was written by the
copyright holder for the initial version, not the modifications.

No time for that at work, but I'll look for a cite over the weekend.

OK, how about one which keeps them unedited, but frames them appropriately?

Indeed, it repeatedly says things about it being under "this License,"
which is GPL v2 and not any other license.
