pierre's message enabled me to identify
the same article in tugboat:


the relevant sections seem to be

   4. smarter ligatures
   5. boundary ligatures
   6. more compact ligatures

some material in other sections may also
be useful in this regard.

Subject: Re: [texhax] Advanced Ligature Handling in .mf and .pl Files

The recent exchanges about this subject made it clear that the documentation
is rather hadr to come by, although Philip Taylor retrieved the reference, for
which I am very grateful, because I had lost my copy.

I have extracted the relevant section of TeXmag V4 N1 into a separate PDF file,
and I offer it here.  At very least, a printed copy is going to go into my
MetafontBook, and others will be scattered in appropriate TeXmf directories.  I
hope this documentation can also find a place where it will be visible in CTAN.
