Should the add_indent function also have a check to avoid making
unnecessary calls to appendStringInfoSpaces when the level is 0?

e.g.
if (indent)
{
    appendStringInfoCharMacro(out, '\n');
    if (level > 0)
        appendStringInfoSpaces(out, level * 4);
 }

V.

if (indent)
{
    appendStringInfoCharMacro(out, '\n');
    appendStringInfoSpaces(out, level * 4);
 }
