Change `org-agenda-repeating-timestamp-show-all' targets
* lisp/org.el (org-closest-date): Rewrite function with less arguments. Improve readability. (org-time-string-to-absolute): Apply changes to `org-closest-date'. Improve docstring. * testing/lisp/test-org.el (test-org/closest-date): New test. This change implies specific repeaters (i.e., ".+" and "++") are no longer treated the same as regular one (i.e. "+") wrt `org-agenda-repeating-timestamp-show-all'. Indeed, only the latter represents multiple dates. The former represent another date only when TODO state changes, which could then skip some occurrences. This fixes issue raised at <http://permalink.gmane.org/gmane.emacs.orgmode/101884> and <http://article.gmane.org/gmane.emacs.orgmode/26154>.

* Version 8.4
|
||||
** Incompatible changes
|
||||
*** ~org-agenda-repeating-timestamp-show-all~ is more selective
|
||||
The variable only applies to ~+~ repeaters, not ~.+~ nor ~++~.
|
||||
** New features
|
||||
*** Org linter
|
||||
~org-lint~ can check syntax and report common issues in Org documents.
