I'm curious: I can reproduce this in ksh88 only.

Nitpick: actually he was not using ksh93. The quoting issue only appeared
in his ksh88. When trying ksh93, he had yet other issues with his scripts.

They look the same to me, expcept that the original date is
shown on Suns (some might be used to this, because ksh88 always did so).
The actual release date is printed on Suns, too, since the t release.
I tried the following in ksh93-d and -n+, I had handy.
echo $(cat << EOF
"double quotes"
'single quotes'
EOF
)
and the quotes remained unchanged.
And I couldn't find a matching entry in the changelogs of ksh93.
But in all ksh88 releases I know, the single quotes change into double quotes.
