[O] Tag completion for ":a_tag:" fails if string "a_tag:" is in headline

[Alain . Cochard]

Hello.

Specifically, I have the simple org file:

* a header :foo:
* blah foo: blah :f

If, after typing the last 'f' above, I type 'M-x pcomplete', I get the
message "No completions of f".

Clearly, the problem is in the "foo:" of the 2nd headline.  Without
it, or with "foo" (or even with ":foo:") in place of "foo:", the
completion is performed to ":foo:" as expected.

Regards.

I use 'emacs -Q -l .emacs.debug', where the .emacs.debug file contains
only

  (add-to-list 'load-path "/home/cochard/Org/Coch-git/org-mode/lisp")

with which I have:
