https://ci.apache.org/builders/svn-warnings currently reports "success" on builds that have compiler warnings, e.g., https://ci.apache.org/builders/svn-warnings/builds/1999/steps/Make/logs/stdio
That's broken: it's supposed to report "warnings" (in yellow) rather than "success" (in green) in that case. The bot's config, [1], has a ShellCommandWithStderrWarning class that's supposed to implement that behaviour, but sometime in the past few years it stopped working. (I _think_ that was at a buildbot master upgrade, but don't catch me on this.) Could anyone look into this? We basically need to figure out how to tell whether stderr is or isn't empty.
