The version of gitiles that powers https://gerrit.googlesource.com/ at the time of

This is probably on purpose, Gerrit also includes this prefix on its JSON output to
prevent injection in scripts.

Indeed, working as intended. Many JSON libraries support adding a special prefix to
make the returned source non-executable in order to prevent XSSI attacks; see for example
https://code.google.com/p/google-gson/issues/detail?id=42

This prefix is always constant for Gitiles, so you can strip the first 5 bytes of the
output. Or up to the first newline, your choice.
