mailinfo: read local configuration

Since b9605bc4f2 ("config: only read .git/config from configured repos", 2016-09-12), we do not read from ".git/config" unless we know we are in a repository. "git mailinfo" however didn't do the repository discovery and instead relied on the old behaviour. This was mostly OK because it was merely run as a helper program by other porcelain scripts that first chdir's up to the root of the working tree. Teach the command to run a "gentle" version of repository discovery so that local configuration variables like mailinfo.scissors are honoured. Signed-off-by: Junio C Hamano <gitster@pobox.com>
