OK, I still cannot read it out of what you wrote in the proposed log message without aid, but in essense the crux of the problem is that invoking "some/path/to/git" finds "some/path/to/git.exe" only when there is no "some/path/to/git" directory at the same time, and if that directory exists, tries and fails to execute that directory, and the change in this patch protects us from that problem. Did I get it right? I'd really prefer to see it more clearly written in the log message so the next person who reads "git log" do not have to ask the same question to you. Assuming that I read it correctly, I think this patch as a whole makes tons of sense as a change to make the invocation more robust. Thanks.
