i used this script, a little clunky but it got the job done
```bash
for file in `find . -type f -print | grep '\.go'`; do
sed '1,/^\/\/ limitations under the License.$/d' $file > $file.tmp;
result=`cat $file.tmp`
if [[ result != "" ]]; then
gofmt $file.tmp &> /dev/null;
if [[ $? == 0 ]]; then
mv $file.tmp $file && gofmt -w $file;
else
rm $file.tmp;
fi
else
rm $file.tmp;
fi
done
```
We add a new protobuf type. Also, protoc changed slightly and remade
some tests, in a way which should have no effects but makes the code
*very* slightly cleaner.
This introduces the first testing code in encoding/proto (whoops)
so that scaffolding is a first draft; if you're looking at this code
and the design is a problem go ahead and fix it.
The purpose of this is to verify that we're actually covering all
the branches in the ingest.ShardedRequest and pb.ShardedIngestRequest
message conversions. (Except the top-level one for a nil request,
which isn't checked by this.)
The coverage report doesn't actually include coverage for the ingest
code, though, so we haven't actually properly tested Compare.
Baby steps!
