While debugging something else, I was quite puzzled to see that
prepare_shell_cmd()
duplicates the command before sending to sh, like:sh -c "git-upload-pack '../testrepo/.git'" "git-upload-pack '../testrepo/.git'"
A Windows programmer myself, initially I thought that it's a bug.
Add a clarifying comment.
