The above citation is from a section which explains how to avoid
warnings.  It is not the place where we document 'require' itself,
only its use to avoid warnings.  So reading that out of context as a
statement of the main purpose of 'require' is a mistake, as 'require'
is fully documented elsewhere in the manual.

In the context of avoiding warnings, I see no problem in mentioning
'require'.
