The "xargs" was missing in Steven's original pipeline.
But be careful, Steven (and others who may be reading),
because xargs may split your list up and invoke "svn add"
multiple times. Check "man xargs" on your system to see
whether you need to be scared; on mine it'll start splitting
once the command line gets beyond 5k bytes.
If there's any danger that you'll need more than that,
you want "svn add --targets". Unfortunately, that seems
to require a genuine filename:
$ svn add --targets -
svn: Reading from stdin is currently broken, so disabled
so you can't use a pipeline as such any more. Then again,
with a list that long you might be glad of a record of
just what you fed to "svn add" anyway.
