[bug #64576] [pdf.tmac] pdf*href option handling insufficiently flexible

[G. Branden Robinson]

Follow-up Comment #5, bug #64576 (project groff):

[comment #4 comment #4:]
> Just completed a fix to allow any input to be used as a valid *roff
identifier. This allows all UTF-8 to be used as well. So both "Known Issues"
in my NewGropdf document are now ticked off. :-)

Wow!  Push, push!  (As Herbie Mann said.  Or Robert Plant.)  I want to see
what this looks like when we don't have `for` yet!

Incidentally, and to motivate my frustration with the `pdfhref` approach, the
following works _terribly_.  The hotspots don't know where to end, going nuts
and electrifying everything after them even without a page break to screw them
up by not calling `pdfmarksuspend` and `pdfmarkrestart`.
