* 'master' of github.com:scmbreeze/scm_breeze: fix rc file suffix in README Return error code from git branch command. Use File.exist over deprecated File.exists Speed up and simplify parse_git_branch Define git functions with parentheses instead of curly braces, so that we can press Ctrl+C to quit the commit prompt without terminating the shell session. (Parentheses run the function in a subshell.)
