Just today, I was editing some prototyping code, which was not backed by version
control. I did a brain-dead "rm *" which killed my project files and Maven
build files. The local VCS came to the rescue, and I got everything back
without a problem.
There was an issue though (IDEA 929):
WHen I restored the IDEA project files, that instance of IDEA locked up. Since
I figured this scenario is not typical use, restarting IDEA was not too bad. It
continued working after the restart.
