FYI: .po,v files pruned in repository

[Jim Meyering]

FYI, I've removed about 26MB from coreutils' po/*.po,v files.
I noticed that the po/ directory was taking up about 60% of
the space in coreutils' repository.  Most of that came from *.po,v files.

I've removed a lot of useless deltas, but was careful to leave any
revision that is referenced by a tag, as well as the first and last of
each file.  FYI, this is acceptable only because those files are
automatically generated.  In other cases, we wouldn't want to do this,
since it deletes a log message for each removed node.
I did the same to the file named `configure'.

Also, the public read-only CVS repository is once again up to date.
