Fix up duplicated duplicated words mostly in comments

In the r10-7197-gbae7b38cf8a21e068ad5c0bab089dedb78af3346 commit I've
noticed duplicated word in a message, which lead me to grep for those and
we have a tons of them.
I've used
grep -v 'long long\|optab optab\|template template\|double double' *.[chS] */*.[chS] *.def config/*/* 2>/dev/null | grep ' \([a-zA-Z]\+\) \1 '
Note, the command will not detect the doubled words at the start or end of
line or when one of the words is at the end of line and the next one at the
start of another one.
Some of it is fairly obvious, e.g. all the "the the" cases which is
something I've posted and committed patch for already e.g. in 2016,
other cases are often valid, e.g. "that that" seems to look mostly ok to me.
Some cases are quite hard to figure out, I've left out some of them from the
patch (e.g. "and and" in some cases isn't talking about bitwise/logical and
and so looks incorrect, but in other cases it is talking about those
operations).
In most cases the right solution seems to be to remove one of the duplicated
words, but not always.

I think most important are the ones with user visible messages (in the patch
3 of the first 4 hunks), the rest is just comments (and internal
documentation; for that see the doc/tm.texi changes).
