It is probably badly worded. It is generally helpful if you do

 - include(), require() *without* output buffering
 - anything *with* output buffering, not generating XML/SGML output

Note that although HTML and XML is permissive on the whitespace you
output, if you do generate some other format (ie. csv file, image, swf
file) with output buffering, and store the results elsewhere, additional
whitespace in unintentional places can be a big pain. It is actually
irrelevant if you use output buffering or not.
