I do not see why you need the egrep. Use sed for that filtering - easy.
Now, using -n option you prevent sed from printing unnessesary line.
After that just print what you need: lines with section number and lines with changes:
Code:
> sdiff rak1 rak2 | grep -n "." | sed -n '/>$/d; /section/p; /[|<>]/p'

Ok, deleting still needed

The only not-nice, the sections with no changes will be in that printout

I could not get it by 'sed'
Easy with nawk:
Code:
>....|
nawk '{if ( ($0 !~ /section/) || (prev !~ /section/) ) print prev; prev=$0;}
        END{if ($0 !~ /section/) print $0;}'

Not clear why it has empty line in beginning and end; so, remove it by :
Code:
>...|nawk NF;
