nit: fix up ifdef guard

[jiayl, 2013/06/06 17:07:37]

Done.

why?

[jiayl, 2013/06/06 17:07:37]

Removed.

[jam, 2013/06/06 16:22:32]

this is redundant from browser_message_filter.h by definition

[jiayl, 2013/06/06 17:07:37]

removed

[jam, 2013/06/06 16:22:32]

[jiayl, 2013/06/06 17:07:37]

Done.

nit: hide this

hmm, but I need to call it from the browser test
