Fix up duplicated duplicated words in comments

Like in r10-7215-g700d4cb08c88aec37c13e21e63dd61fd698baabc 2 years ago,
I've run
grep -v 'long long\|optab optab\|template template\|double double' *.{[chS],cc} */*.{[chS],cc} *.def config/*/* 2>/dev/null | grep ' \([a-zA-Z]\+\) \1 '
and for the cases that looked clearly wrong changed them, mostly by removing
one of the duplicated words but in some cases with other changes.
