Bug: Properties don't work in clocktable [9.0.5 (release_9.0.5-305-g21797c @ /Users/dale/.emacs.d/el-get/org-mode/lisp/)]

[Dale <dale@codefu.org>]

For me, clocktable's :properties option is including columns for the
properties, but is never including the actual values for those properties.
This *may* be a bug, specifically in org-clock.el line 2590:

    (pcase-dolist (`(,level ,headline ,ts ,time . ,props) entries)
      ...)

I believe the ". ,props" should be just ",props", since I think the list
of properties here is its own list, and not the cdr of entries:

    (pcase-dolist (`(,level ,headline ,ts ,time ,props) entries)
      ...)

To reproduce this problem using org-mode HEAD, evaluate the following:

    (switch-to-buffer (generate-new-buffer "*org mode test*"))
    (org-mode)
    (insert "* Time
    :PROPERTIES:
    :FOO:      bar
    :END:
    :LOGBOOK:
    CLOCK: [2017-02-18 Sat 10:50]--[2017-02-18 Sat 10:51] =>  0:01
    :END:

    #+BEGIN: clocktable :compact t :properties (\"FOO\") :maxlevel 2
:scope subtree
    #+END:
    ")
    (goto-char (point-max))
    (forward-line -1)
    (org-dblock-update)

Expected result which includes the property value:

#+BEGIN: clocktable :compact t :properties ("FOO") :maxlevel 2 :scope subtree
#+CAPTION: Clock summary at [2017-02-18 Sat 10:59]
| FOO | Headline     | Time    |
|-----+--------------+---------|
|     | *Total time* | *0.02h* |
|-----+--------------+---------|
| bar | Time         | 0.02h   |
#+END:

Observed result from HEAD, note no property value:

#+BEGIN: clocktable :compact t :properties ("FOO") :maxlevel 2 :scope subtree
#+CAPTION: Clock summary at [2017-02-18 Sat 10:54]
| FOO | Headline     | Time    |
|-----+--------------+---------|
|     | *Total time* | *0.02h* |
|-----+--------------+---------|
|     | Time         | 0.02h   |
#+END:

I'll take every opportunity I can to thank all the people who work to
make org-mode so indispensable!  Thank you!
