Introduce <branch>@{push} short-hand to denote the remote-tracking branch that tracks the branch at the remote the <branch> would be pushed to. * jk/at-push-sha1: for-each-ref: accept "%(push)" format for-each-ref: use skip_prefix instead of starts_with sha1_name: implement @{push} shorthand sha1_name: refactor interpret_upstream_mark sha1_name: refactor upstream_mark remote.c: add branch_get_push remote.c: return upstream name from stat_tracking_info remote.c: untangle error logic in branch_get_upstream remote.c: report specific errors from branch_get_upstream remote.c: introduce branch_get_upstream helper remote.c: hoist read_config into remote_get_1 remote.c: provide per-branch pushremote name remote.c: hoist branch.*.remote lookup out of remote_get_1 remote.c: drop "remote" pointer from "struct branch" remote.c: refactor setup of branch->merge list remote.c: drop default_remote_name variable
