Yeah; you're still changing the default output format.
Please don't do that; give people a -verbose switch or whatever, but don't 
say "well, if you have a script that parses this, then you need to either 
teach it to parse the new format, or have it pass a new switch that old 
versions of the tool won't accept".

As it stands now, there is no way for a program to invoke 'fs getcache' in 
a way that is guaranteed to produce the output format it needs without 
knowing in advance whether it has your patch or not.
