After years of use I've come up with some improvements to the `JENKINS_HOME.gitignore` example. - Major performance improvement: On very large Jenkins installations that have been running for more than one year, there tends to be many builds (hundreds of thousands of builds). The `builds` directory of these jobs contain millions of files which would cause Git to hang for several minutes on simple commands like `git status` and longer for committing changes. `strace` was used on Git to figure out the performance impact and this proposed change includes the optimization. I also added a clear comment explaining the line's purpose. - There's an example for how to include Jenkins encryption keys, and there's a disclaimer informing the user why they shouldn't but still giving an example. - Comments have been reworded and slightly reformatted to be a little more clear.
