Thanks for the report. Bash has, for some years, allowed EOF/EOS to 
terminate a command substitution in certain circumstances, but this really
only shows up when you're expanding it inside a here-document. There is a
(relatively cryptic) warning message, but that only shows up in development
builds. It seems reasonable to make the behavior when expanding here-
documents match the behavior outside them.
