"Unused values" tests amalgamated into one

[Paul Eggert]

"make check" was outputting things like this:

  4: Unused values                                ok
  5: Unused values                                ok
  6: Unused values                                ok
  7: Unused values                                ok
  8: Unused values                                ok
  9: Unused values                                ok
 10: Unused values                                ok
 11: Unused values                                ok
 12: Unused values                                ok
 13: Unused values                                ok
 14: Unused values                                ok

which was a bit confusing.  I revamped all the "Unused values" test
into one, as follows.

2006-01-29  Paul Eggert  <address@hidden>

        * tests/input.at (AT_CHECK_UNUSED_VALUES): Remove.  Instead, do
        all the test at once.  This makes the output easier to read in the
        normal case.
