Credential helpers are asked in turn until one of them give positive response, which is cumbersome to turn off when you need to run Git in an automated setting. The credential helper interface learned to allow a helper to say "stop, don't ask other helpers." Also GIT_TERMINAL_PROMPT environment can be set to false to disable our built-in prompt mechanism for passwords. * jk/credential-quit: prompt: respect GIT_TERMINAL_PROMPT to disable terminal prompts credential: let helpers tell us to quit
