Merge branch 'dg/local-mod-error-messages'

* dg/local-mod-error-messages:
t7609-merge-co-error-msgs: test non-fast forward case too.
Move "show_all_errors = 1" to setup_unpack_trees_porcelain()
setup_unpack_trees_porcelain: take the whole options struct as parameter
Move set_porcelain_error_msgs to unpack-trees.c and rename it
