Updating repository while fixing a bug

It may be helpful to never update your local stuff if you have files checked out and you are working on something. If you do, it may further introduce bugs into your work, which may cause frustration. This is particularly important if you are in the middle of fixing a troublesome bug. By updating, it would change the bug hunting environment, which could cause you to lose all currently gathered information.
