Allow to control where the replace refs are looked formh/replace-refs
It can be useful to have grafts or replace refs for specific use-cases while keeping the default "view" of the repository pristine (or with a different set of grafts/replace refs). It is possible to use a different graft file with GIT_GRAFT_FILE, but while replace refs are more powerful, they don't have an equivalent override. Add a GIT_REPLACE_REF_BASE environment variable to control where git is going to look for replace refs. Signed-off-by: Mike Hommey <mh@glandium.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
