[Docutils-users] Replace bug

[<mic...@gm...>]

The following fails:

replace_bug.rst:

    |Bug|_
    
    .. |Bug| replace::
        A. Bug: the initial causes problems.
    .. _Bug: 


Failure:

    $ rst2html.py --version
    rst2html.py (Docutils 0.14, Python 2.7.13, on darwin)
    
    $ rst2html.py replace_bug.rst > replace_bug.html
    replace_bug.rst:3: (ERROR/3) Error in "replace" directive: may contain a single paragraph only.
    replace_bug.rst:3: (WARNING/2) Substitution definition "Bug" empty or invalid.
    
    .. |Bug| replace::
             A. Bug: the initial causes problems.
    replace_bug.rst:1: (ERROR/3) Undefined substitution referenced: "Bug".


This was based on the replacement example from the documentation:

			
|Python|_ 

.. |Python| replace::
	 Python: A great language!
.. _Python:

A workaround is to escape the space *and* include an additional space, but this is very ugly.  Is there a better solution?

|Workaround|_

 .. |Workaround| replace::
	 A.\  Bug: the initial causes problems.

.. _Workaround:

Am I misreading the documentation/misusing replacements or should I file a bug report?
