OK, it seems that indeed it would then be best to document:

     If you want to make sure no such errors occur on large output,
     instead of
     $ sort | head
     use
     $ sort > file; head file

as an _easy to remember_ alternative amongst the many.

And OK put this in some general place, and have the sort, etc. pages
link to it. Thanks.
