Could you please name it in a way that it ends with '_fuzzer'. I think that we
rely on that format name in Chromium for some reason.

`"blink_text_codec_" + target_name + "_fuzzer"` would be good

[Charlie Harrison, 2017/03/03 19:33:55]

Done.

Do you have the same seed corpus set for all the configs, or a separate for each
of them?

[Charlie Harrison, 2017/03/03 19:33:55]

Right now there is just one named "blink_text_codec_fuzzer" that jsbell
uploaded. I am not sure what we should do and would appreciate advice!
