The anchor is in this paragraph:
Nonincremental search for a regexp is done with the commands
‘re-search-forward’ and ‘re-search-backward’. [...]
But I thought you wanted to refer to the description in the paragraph
before that, that is:
Forward and backward regexp search are not symmetrical, because
regexp matching in Emacs always operates forward, starting with the
beginning of the regexp. Thus, forward regexp search scans forward,
trying a forward match at each possible starting position. Backward
regexp search scans backward, trying a forward match at each possible
starting position. These search methods are not mirror images.
The problem is that most people will only read forward. Did I miss
something?

So far, I'm outvoted.
Michael.
