Native histograms without observations and with a zero threshold of zero look the same as classic histograms in the protobuf exposition format. According to https://github.com/prometheus/client_golang/issues/1127 , the idea is to add a no-op span to those histograms to mark them as native histograms. This commit enables Prometheus to detect that no-op span and adds a doc comment to the proto spec describing the behavior. Signed-off-by: beorn7 <beorn@grafana.com> |

Making changes to textparse lexers
In the rare case that you need to update the textparse lexers, edit promlex.l or openmetricslex.l and then run the following command:
golex -o=promlex.l.go promlex.l
Note that you need golex installed:
go get -u modernc.org/golex
