Indeed, the documentaion says the default regexps are compatible with
emacs regexp.  Even there is a link to emacs regexp node. But emacs
regexps understand the syntax `\{3,\}'.  That's the point I mean by
"incorrect documentaion".
So, I used 
    $ find . -type f -regex-type posix-extended -regex '.{3,}'
instead.  This latter command works perfectly.

So, the emacs regexp style of find is not compatible with emacs regexp!
Sadly, that led me to waste time to investigate why my regexp did not
work.
