Thats because the use of curlies in a variable name is for
delimitation, and does not act as an override to the quoting syntax as
James suggested.
consider:
BLAH=Test
echo ${BLAH}Me
which produces the output "TestMe".
This can't be done quite this way without the use of the delimiting
braces.
They do not have any affect on quoting though. (if they did, we'd all
be having great problems.)
