make this a CHECK if anything, otherwise FromValue() will be compiled out.

Done.

see comment in previous CL about using JSONWriter for this rather than
ListValue/IPC.

see

[aboxhall, 2014/07/18 21:08:52]

Done. (Not using OPTIONS_PRETTY_PRINT though, is that ok?)

[not at google - send to devlin, 2014/07/18 22:02:18]

so like I mentioned in the other CL I don't really know the purpose for this
method anyway, since I can't find it called from anywhere. but presuming that
the log is for human consumption then having OPTIONS_PRETTY_PRINT sounds like
the right thing.

Done.
