revert: Simplify and inline add_message_to_msg

Browse Source 
The add_message_to_msg function has some dead code, an unclear API,
only one callsite.  While it originally intended fill up an empty
commit message with the commit object name while picking, it really
doesn't do this -- a bug introduced in v1.5.1-rc1~65^2~2 (Make
git-revert & git-cherry-pick a builtin, 2007-03-01).  Today, tests in
t3505-cherry-pick-empty.sh indicate that not filling up an empty
commit message is the desired behavior.  Re-implement and inline the
function accordingly, with a beneficial side-effect: don't dereference
a NULL pointer when the commit doesn't have a delimeter after the
header.
