# The mailmap. A repository whose commits and tag carry an old ident gets a
# .mailmap at HEAD renaming it, and every page that shows an ident is checked
# for the new name, along with the author search. Only that blob is read, so
# a mailmap set in the repository's config or kept on another branch is
# checked to change nothing. Then the flag is turned off globally and for the
# one repository.

# The last commit is by the old ident and stamped now, so the stats page,
# which counts only recent periods, has it to show. The side branch holds a
# mailmap of its own, and the repository config points at two more, all of
# which cgit leaves alone.
