Without this patch applied we would print one empty line before every other line in the structured log output. On Android every one of these lines is prepended with a timestamp and pushed to the logcat, making it measurably larger. With this patch applied a single batch of XPCShell tests (roughly half the tests) results in a 205 MiB logcat file instead of a 220 MiB one.
