[PATCH v2] *: fix typos which duplicate a word

[Andrei Rybak <rybak.a.v@gmail.com>]

Fix typos in documentation and code comments which repeat various words.
These typos were found by searching using scripts like this:

	for w in $(grep '^....$' /usr/share/dict/words)
	do
		git grep -P "\b$w $w\b"
	done

Thanks to Felipe Contreras for review.

Changes from v1:

  - added "*: " as area prefix to follow example of Derrick Stolee
    https://lore.kernel.org/git/c40ad4a058a75d57adc97b8252ad0f57600b8d86.1623085069.git.gitgitgadget@gmail.com/
  - Dropped change in t/t6416-recursive-corner-cases.sh where I misread a
    sentence and the duplicated word "that" is used correctly. Quote for
    reference:

      ... so we use one path whose name is arbitrary in the virtual merge base X
      between D and E" and then further let the rename detection to notice that
      that arbitrary path gets renamed ...

    where first "that" is a conjunction between clauses "we let" and "path gets
    renamed" and second "that" is a determiner to qualify "arbitrary path" to
    refer to "one path" mentioned in the first clause
