Bug: Missing prompt label in capture template expansion

[Aankhen <aankhen@gmail.com>]

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

     http://orgmode.org/manual/Feedback.html#Feedback

Your bug report will be posted to the Org-mode mailing list.
------------------------------------------------------------------------

STEPS TO REPRODUCE:
1. Add this to the list of capture templates:
    ("t" "Test" entry (file "z:/Temp/t.org")
     "*** TODO %^{Foo} [[bar:%^{Bar}][Bar]]")
2. Run org-capture.
3. Fill in a value for “Foo” when prompted and press Enter.

EXPECTED RESULTS:
Prompted for second value, with label “Bar”.

ACTUAL RESULTS:
Prompted for second value, with label “ ” (single space).

NOTES:
I tried this using org-mode from git (commit id:
b23d35de06c229db84472d893c8645c63896a6cd) after starting Emacs with
‘emacs -Q’ to ensure there was no interference.  A couple of
variations on the template above work fine, correctly showing the
label when prompting for a value:

* No prompts before the one in the link: ("t" "Test" entry (file
"z:/Temp/t.org") "*** TODO [[bar:%^{Bar}][Bar]]")
* No link description: ("t" "Test" entry (file "z:/Temp/t.org") "***
TODO [[bar:%^{Bar}][Bar]]")

Config follows…
