revert.c: defer writing CHERRY_PICK_HEAD till it is safe to do so
do_pick_commit() writes out CHERRY_PICK_HEAD before invoking merge (either via do_recursive_merge() or try_merge_command()) on the assumption that if the merge fails it is due to conflict. However, if the tree is dirty, the merge may not even start, aborting before do_pick_commit() can remove CHERRY_PICK_HEAD. Instead, defer writing CHERRY_PICK_HEAD till after merge has returned. At this point we know the merge has either succeeded or failed due to conflict. In either case, we want CHERRY_PICK_HEAD to be written so that it may be picked up by the subsequent invocation of commit. Note that do_recursive_merge() aborts if the merge cannot start, while try_merge_command() returns a non-zero value other than 1.
