I spent some time digging into this and the attributes are reloaded
before each pick. This is because check_updates() called by
unpack_trees() calls git_attr_set_direction(GIT_ATTR_CHECKOUT) at the
start of the function and git_attr_set_direction(GIT_ATTR_CHECKIN) at
the end of the function. This has the effect of dropping all loaded
attributes as git_attr_set_direction() calls drop_all_attr_stacks() when
the direction is changed.
