To expand on this.. not only local scope vars, but global..

var
  global: integer = 0;

I agree is much clearer than leaving it to the assumption:

// this will be zero.. bad assumption
var
  global: integer;

This would be a good global habit to get into also for globals:

var
  global: Trec autoinit;

or

var
  global: Trec;
begin
  init(global)
end;

The problem with the above is that sometimes the global is further away 
in your code than you eyes can see, hence the inline declaring of 
initialization "right while you are at it" is safer for humans.
 
Relying on global variables being zero is bad, I agree.. and they should 
be iniitalized by habit.. too. Especially when one copies global code 
into local code does a problem exist, if one made the assumption of the 
globals being initialized then (which may have been true, but now that 
they are no longer globals... problem time).
