That is so confusing... if the major issue is that if you wanted to add
more lines before of after the else, then simply wrap the code with
begin..end blocks.  If you think that it is too much typing, use a typing
tutor to improve you typing skills or use a decent editor that can
automatically add those begin/end blocks for you (normally called "code
templates").

Non-confusing end result looks like this:

  if a then
  begin
    DoSomething;
  end
  else
  begin
    DoOtherThing;
  end;

or

  if a then
  begin
    DoSomething;
  end
  else begin
    DoOtherThing;
  end;


Lets take Lazarus IDE as an example of a good editor:
USAGE:
  * type the first few letters and then press Ctrl+J

ifb   - if statement
b     - begin end
be    - begin end else begin end
bg    - begin end
ifb   - if statement with begin end
ifeb  - if then else with begin end blocks
ife   - if then (no begin/end) else (no begin/end)


And these are just the begin/end and if statement templates. There are
many, many other templates too. So your "solution" just seems like to much
work modifying the compiler and the end result is code the developer cannot
understand or finds very confusing.

But then it's like you said: It's your patch, use it or don't. :)
