Perhaps it has. But in that mail from last year, the string in question was:
echo `echo '${'`
But by my current understanding, the answer is still the same - inside
the backticks, no \ appears, so all characters are passed literally
to the subshell between the two ``. Then, inside the subshell,
you are executing echo '${', which has well-defined semantics,
so the overall output is still ${. So even though my interpretation
may have refined a bit, the sample in that older email still
results in the same string by either interpretation.

I look forward to seeing what you come up with. I wish I
could help by coming up with a solution myself, but have not
had time to do so yet.
