fz@fz:~/grub/grub2.git$ rgrep -E "^[[:blank:]]+$" *|wc -l
2273
fz@fz:~/grub/grub2.git$ rgrep -E "^[[:blank:]]+$" *|sed -e 's/:.*//'|uniq|wc -l
170

Anyone wants me to do 
find . -type f -print0 | xargs -0 sed -i -r -e 's/^[[:blank:]]+$//'
or does someone object?
[:blank:] doestn't contain these ^L chars.

By the way `git diff --color' shows if you introduce such a line with
red, but strangely not when you remove one.
