On February 27th I submitted a patch proposal to fix HTML export of line 
number references in source code fragments. The discussion leading up to 
the patch can be found in the thread:

    <http://thread.gmane.org/gmane.emacs.orgmode/35810>

As far as I can see, it is not in the source tree as of revision 62d4dd, 
but the problem still remains.

I am grateful for feedback on its lackings, if the patch is deemed 
unsatisfactory in any way. In case it simply got lost amidst all the 
other traffic, I resubmit it, updated so it applies to the current revision.
