Parse error for here document inside an if with variable

[skovhus]

Parse fails for the entire document when you have a here document inside an if, that contains a variable as the first expression.

MWE:

if true; then
  a_string='some stuff to cat'
  cat <<XXX
${a_string}
XXX
fi

The issue does not occur if:

• not inside an if
• there is anything except newlines before ${a_string}, including whitespace

It also fails everywhere.

This seems to have been fixed in the newer version of the grammar
