Subject: log: add log.mailmap configuration option
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=e6bb5f78fb351c89a80826befda3c8f06f91f249;p=git.git

log: add log.mailmap configuration option

Teach "log.mailmap" configuration variable to turn "--use-mailmap"
option on to "git log", "git show" and "git whatchanged".

The "--no-use-mailmap" option from the command line can countermand
the setting.
