It turned out that for my purpose I only needed some of the instructions 
at that site.

It took me two tries, but on the second, these commands sufficed:

   540  git clone git://perl5.git.perl.org/perl.git perl4podhtml
   541  cd perl4podhtml/
   542  git remote rm origin
   543  vi .git/config
   544  git filter-branch --subdirectory-filter ext/Pod-Html/ -- --all

At this point, the top-level directory merely contained the directories 
formerly found in ext/Pod-Html/.  And 'git log' and 'git blame' 
indicated that the history had been preserved.  So I quit right there.

After the usual finagling and some renaming, I was able to put a 
repository on github:

https://github.com/jkeenan/opodhtml

It currently has two branches:  'blead', which should represent the 
state of ext/Pod-Html in Perl 5 blead as of today; 'master', which will 
be my master branch for refactoring, adding tests, giving Pod-Html the 
old Phalanx treatment.

Thank you very much.
