In build 3326, the new idea.bat seems to be broken (on Windows 2000).
Quotes were removed from the loop that deals with the idea.vm.options file
and IDEA won't start up with yourkit complaining:
YourKit Java Profiler 4.0.3 cannot start: unknown option 'port'
YourKit Java Profiler 4.0.3 agent usage: -Xrunyjpagent[:help]|[:]]>,
Using the old idea.bat file works fine.
(the optoin "-Xrunyjpagent:port=10100" gets truncated to
without the quotes).
