[PATCH] 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

I'm not sure what to put as the "area: " prefix for this patch, as it touches
both docs and code comments.
