Subject: from Tim van der Molen:

- State that ftell() and ftello() return -1 on error rather than just a
  non-zero value. The latter is not specific enough, because these
  functions can also return non-zero on success.

- For clarity and search-friendliness, don't refer to fgetpos() and
  fsetpos() as "the others", but mention them by name.
