Teach commands in the "log" family to optionally pay attention to the mailmap. * ap/log-mailmap: log --use-mailmap: optimize for cases without --author/--committer search log: add log.mailmap configuration option log: grep author/committer using mailmap test: add test for --use-mailmap option log: add --use-mailmap option pretty: use mailmap to display username and email mailmap: add mailmap structure to rev_info and pp mailmap: simplify map_user() interface mailmap: remove email copy and length limitation Use split_ident_line to parse author and committer string-list: allow case-insensitive string list
