I tend to agree with "Anyways" above ;-) simply because I found the
long paragraph more confusing than enlightening, leaving me wonder
"why is the user using different settings for author and committer
name" at the end, which _is_ an irrelevant point in the issue being
addressed.
The real issue is that this commented-out sample hook uses "author"
ident for the sign-off, while all the rest of Git (i.e. all callers
of append_signoff() in sequencer.c) use committer ident.
If anything to be changed to this patch, I would say its "should be"
in the log message can be clarified with "why", perhaps like:
Sign-off added should be that of the "committer", not that of
the "commit's author"; that is how the rest of Git adds sign-off
using sequencer.c::append_signoff().
Thanks.
