This will be a little delayed; if I apply the straightforward patch I
intend (attached), I find that the links in
contrib/mom/examples/mon_premier_doc.pdf that have Latin-1 characters in
them stop working.  (Many other links to tags, including the TOC forward
references in Bertrand's automake.mom, and the numerous links to tags
every which way in mom-pdf.mom, work fine.)

I think I know why those Latin-1-tagged links don't work.  I think it's
the "node"/encoding problem,[1] which means I need to finish the work on
making the `\X` escape sequence read its argument in copy mode.  As I
recall, Deri already made gropdf(1) interpret sequences like "\[u1A2B]"
in its device "specials" ("device control commands" as the formatter
understands them), and in copy mode, that is exactly what `\X` should
deliver.

Well, at least I'm clear on my next task...

Apart from that, the mom examples are as beautiful as ever.

Again, there's no need to seriously consider the attachment at present;
it is simply an indication of what I attempted, and where my head is at.

Branden
