"git cherry-pick foo" has always reported success with
"Finished one cherry-pick" but "cherry-pick --strategy"
does not print anything. So move the code to write that
message from do_recursive_merge() to do_cherry_pick()
so other strategies can share it.
This patch also refactors the code that prints a message
like "Automatic cherry-pick failed. <help message>". This
code was duplicated in both do_recursive_merge() and
do_pick_commit().
To do that, now do_recursive_merge() returns an int to signal
success or failure. And in case of failure we just return 1
from do_pick_commit() instead of doing "exit(1)" from either
do_recursive_merge() or do_pick_commit().
