I meant that 2/3 of the condition here can be eliminated, since postfix is
ignored in the frogium and webdriver cases.

[Emily Fortuna, 2012/01/24 17:20:22]

Right. I ended up fixing it in a new CL here
(https://chromiumcodereview.appspot.com/9117010/), because I originally had to
revert this one since this checkin broke all of frog *except* Windows! (the line
that caused the problem was 187 in buildbot_annotated_steps.py)
