And that's something *I* don't like. You never know which END belongs to 
wheach BEGIN. I always column align all ENDs to their corresponding 
BEGINs. That makes it much easier to check if some of these keywords are 
missing:

if a then
    begin
    xxxxx
    .....
    yyyyy
    zzzzz
    end;

To me BEGIN and END clamp a logical block (that is indented by 3 
characters) so they need to be aligned with all commands of the same 
level. Each next block of IF, WHILE, REPEAT etc. is indented again by 3 
characters. By following this strict rule the code is much more readable 
to me.
