[O] org-log-post-message: is it properly reset?

[Michaël Cadilhac]

Hi there;

>From time to time, I have some spurious "Entry repeats" messages when
editing tasks that have no repetition.  I've tracked that down to
org-log-post-message being message'd in org-store-log-note, and I
can't really see anywhere where the variable is reset.  Should it be
reset after it's used in org-store-log-note?

Additionally, why is it defvar'd twice?

Cheers;
M.
