did git cl format break this line like that?

also, j_client_id_namespace

[bburns, 2016/02/23 19:25:38]

No, its > 80 cols, so we have to line break, that's the correct indent.  (I
agree its ugly)
 
Done.

seems like we need a better name than namespace here.

Namespace seems like the correct name, but I'm ok with other suggestions.
