Overhead!

If you use 8 spaces instead of one tab,
that's using up 7x more space!

Consider:

     # calculates the extra space required to
     # use the given number of spaces/tab.
     size()
     {
         count=`grep -RIo "\`printf \"\t\"\`" . | wc -l`;
         perl -e "print $count*$(($1-1))/1024/1024 . \" MB\n\"";
     }

     Then in in a git working tree:

         size 8; # 1.28701210021973 MB
         size 4; # 0.551576614379883 MB

     In a linux kernel working tree:

         size 8; # 61.4902725219727 MB
         size 4; # 26.3529739379883 MB

Conclusion:

     Yikes!


I hate tabs, but I can't argue with that!
