No.  As David DiGiacomo stated, it's because the here document terminator
string was unquoted.  Quoting any character in the here document string
causes the shell to simply copy the document itself, ignoring things like
dollar signs and back-quotes.

Evidently the map folk feel this way also - the last maps had a quoted
here document terminator.
