Since gerrit:131263 <https://gerrit.wikimedia.org/r/131263/> , it seems
to me that the excellent mwpfh is going to be used more and more

Am I right? For example, the DuplicateReferences detection and fix in
reflinks.py could be brightly refactored without regular expressions.
Or are we supposed to do the opposite conversion, where possible?
