Gah, good catch.  Fixed in my local copy.  I also added a bit of extra
error checking to try to make sure the years were sane.

Since it's a big patch, I'll see if there are any more comments before
sending an update.

Yeah.  I'd also tried to avoid touching the gcc tests in this patch,
so hopefully the same filter would be OK when adding the extra year.

The script applies a similar filter to the libjava testsuite.  I wasn't
sure what do about libstdc++ though, since its testsuite seems less like
a random collection of tests.  I'll cross-post any libstdc++ stuff to
the libstdc++ list once the GCC side has settled down.

I think we should also update the year in the documentation (possibly
including the READMEs).  There are also awk scripts, random shell
scripts, OCaml generators, etc., so it's probably easier to list what
should be left out rather than what should be included.  The current GNU
guidelines seem to actively encourage a blanket update.

Agreed on the historical changelogs though.  It does seem silly to
update those.

OK, thanks for the heads up.  The libstdc++ and libjava changes the
ones I'm least certain about.
