Heeding what is in the search string means nothing - or anything.

What is in the search string is a search pattern.  How it is
interpreted is the question.  Literal matching of whitespace
chars is one such interpretation.

I've already agreed that more than one whitespace char in
a row is a reasonable indication that the user wants/expects
whitespace chars to be matched literally.

Why?  Because with lax whitespace matching there is never any
reason to type multiple, contiguous whitespace chars - it
serves no purpose.

(But see also what I wrote about pasting copied text that
might contain multiple, contiguous whitespace chars.)

What is not obvious is whether whitespace search should be
changed away from literal matching just because there are
not (no longer) multiple such chars in a row in the search
pattern.  That was the subject of the text you quoted.
