Checking the file into Git, don't want it to change on its own.

Although, I personally enjoy sometime looking in there and seeing how many times I ran spr:

showPRLink: true
logGitCommands: true
logGitHubCalls: true
statusBitsHeader: false
stargazer: true
runcount: 2245

That's a lot of times! I'm only getting started :-) Already proving useful.

The main reason for the counter is for the stargaze prompt, so I'm ok with this change.
I'm not sure I understand why you are checking in the user config file?

[leoluk]

I have all config files in my home directory checked into Git for synchronization :)
