Downcasing 'P' and 'A' would make this fit better when it appears in
the "git shortlog --no-merges" output, I think. Or perhaps
[PATCH] pretty: allow to add LF only after non-empty string
or something may fit even better.

Appending at the end in this case does not make less sense than
inserting at the right place in the middle. Noticing that earlier
ones are all about LF, perhaps
NO_MAGIC
ADD_LF_BEFORE_NON_EMPTY
ADD_LF_AFTER_NON_EMPTY
DEL_LF_BEFORE_EMPTY
ADD_SP_BEFORE_NON_EMPTY
may make more sense?
An obvious question that would come to the reader's mind would be if
we also want ADD_SP_AFTER and DEL_SP_BEFORE for completeness, once
the list is ordered in a more logical way like we see above.
I am not suggesting to add these two right now, but we still must
think about them before adding this new one, because it would affect
the choice of the letter used for this new one. It is irresponsible
to say "I do not need it, so somebody else can add them later",
without making sure that somebody else can later choose sensible
letters that make the parallel between those two they are adding
with the existing ones.
We have '+' and '-' as a matching pair that adds or deletes a LF
before the expansion, and we are adding '*' to that group to make
the repertoire <add before non-empty, del before empty, add after
non-empty>. On the SP side, we currently only use ' ', whose
counterpart on the LF side is '+'. Can we easily find counterparts
for '-' and this new '*' for the SP side, when we want to add "add
after non-empty" and "delete before empty", or would it become
easier if we chose something other than '*', and if so what letter?

Here the subject is expanded, LF is added, and then the subject is
expanded _again_ before 'Thanks'. That does not sound like a
realistic example that shows off the situation in which this new
feature becomes useful.

Thanks.
