// The original version for this compresses whitespace and suppresses newlines
// I can see no good reason to do this, and it actually helps preview to keep
// whitespace, especially if the html comes from a filter that generated it
// from text (ie: inside '<pre> tags)
//
// Otoh doing it takes us closer to what the html rendering would
// be. We should actually switch on/off according to pre tags
// Compress whitespace and suppress newlines
// Note that we independantly add some newlines to the output text in the
// tag processing code. Like this, the preview looks a bit more like what a
// browser would display.
// We keep whitespace inside <pre> tags
