@tillrohrmann There exists StringUtilsTest with small test.
One of the TravisCI errors was a timeout and the other killed by the
watchdog. Are timeouts being reworked to use RetryOnException or similar?
@uce It looks like toShortString is used for more than debugging and tests
so I'd go for a separate PR.
