...This sounds great, except if the cause of the problem/solution that made you dig in the source code is a change that was not committed yet, and so did not have its version control number bumped appropriately, and of course any source code changes would not be stored in the version control repository in this case...
Good point. Me, I have a rule that "if it's not under source-code control it doesn't exist" and will not use code in production that has not been checked in, but you're right that this might happen.
