merge: simplify merge_trivial() by using commit_list_append()

Browse source 
Build the commit_list of parents by calling commit_list_append() twice
instead of allocating and linking the items by hand.  This makes the
code shorter and simpler.  Rename the commit_list from parent to parents
(plural) while at it because there are two of them.
