[docs] [issue17047] Fix double double words words

[Serhiy Storchaka]

> Serhiy and Mathew, could you post your search re's or scripts to use again on occasion?

For example:

  find * -type f -name '*.[ch]' -exec egrep -n '\b([a-zA-Z]+) \1\b' '{}' + | grep -v 'long long' | egrep --color '\b([a-zA-Z]+) \1\b'
  find * -type f -name '*.py' -exec egrep -n --color '\b([a-zA-Z]+) \1\b' '{}' +

And similar one-time one-liners for *.rst, *.txt, etc.
