Background
I use the git source control interface provided by Xcode. Typically, I edit several files, then commit only a subset of related files at a time. To exclude some files from a particular commit, I simply uncheck the checkbox next to it in the editor. Rather than click the commit button, I usually use the key combination Command + Return, which commits and dismisses the window.
Problem
Since I began using Xcode 5, there have been several cases where Xcode commits all files, regardless of which files I have checked or unchecked. I cannot figure out if I am pressing some other key combination that does this, or if this is just a bug in Xcode 5. Anyone having this problem?
