This was whittled down to a compatibility wrapper around the more flexible git_prompt() in1cb0134f(refactor git_getpass into generic prompt function, 2011-12-10), waiting for the final callers to go away. That happened in791643a8(imap-send: use git-credential, 2014-04-28) when imap-send learned to use the credential interface.
