Bug: Agenda has no tasks in master [9.1.13 (release_9.1.13-738-g673165.dirty @ c:/D-Drive/bin/org-mode/lisp/)]

[Bernt Hansen <bernt@norang.ca>]

Hi Aaron,

I updated to the latest master this morning and my agenda no longer has
any tasks in it.

I think this commit breaks my agenda:

commit c9dd7a6a9de34b8094ad6a419260fcc1214cc791 (HEAD)

    org-agenda: one-armed .if. -> .when.

    * lisp/org-agenda.el (org-agenda-mode):
    (org-agenda-undo, org-agenda):
    (org-agenda-get-restriction-and-command):
    (org-batch-agenda-csv, org-fix-agenda-info):

    (org-agenda-date-later-minutes, org-agenda-diary-entry-in-org-file):
    (org-agenda-add-entry-to-org-agenda-diary-file):
    (org-agenda-bulk-unmark, org-agenda-to-appt): Convert .if. without
    .else. to .when,. or .unless. in the case of .(if (not ...)).
    (org-batch-agenda-csv): Also convert while-catch to dolist.
    (org-agenda-prepare): Also simplify a quasiquoted structure.
    (org-agenda-entry-text-hide): Also convert a bogus .mapcar. to
    .mapc..
    (org-compile-prefix-format): Also convert sequential .if.s to
    .cl-case..

The following hunk is NOT a one-armed if and you lost the else part
(the last - line):

       ;; expanding tags within `org-make-tags-matcher'
       (org-agenda-prepare (concat "TAGS " match))

When I revert this change my agenda works again.

Please fix :)

Thanks,
