This option should be hyphenated rather than underscored.

I saw others here that had underscores and thought I was following a convention
(albeit a broken one). Looking more carefully now I see that the options are
riddled with inconsistencies. E.g. --local_ip, --record_to_file,
--replay_from_file, --use_browser_controller, but --vm-options,
--write-debug-log, etc.

Anyway, while I'm unhappy to see we are so inconsistent, I'm glad that that
allows me to change this to hyphens :-)
