[docs] Link to heapq source from docs.python.org not working

[Matthew Woodcraft]

http://docs.python.org/library/heapq.html contains a link to the heapq source,
at
http://svn.python.org/view/python/branches/release27-maint/Lib/heapq.py?view=markup

I noticed today that that page isn't working properly.

It's saying
