(Find source files, expand tab chars to their on-screen length, print if 
>= 80, count lines)

~/linux-2.6.12 >
  find . -type f "(" -iname "*.c" -o -iname "*.h" -o -iname "*.S" ")" -print0 |
  xargs -0 perl -pe '1 while s/\t+/" "x(length($&)*8-length($`)%8)/e' | \
  perl -ne 'print if/.{80}/' | \
  wc -l
208420

If the indent was just 4 spc wide, the number of extending
