Not at all odd.  Most coding standards I've seen insist on braces
on all controlled statements - if, while, do, for, etc.  Particularly
when developing code it avoids problems when inserting statements.  
For instance:

Original code:

  if (x < y)
    x = y;

Then you realise you want to do something as well.  It's very easy
to end up with something like:

  if (x < y)
    x = y;
    a[x] = y*y;

and not notice that the second statement isn't actually controlled
by the if.  It's even worse if you're used to seeing K&R type
braces like

  if (x < y) {
    x = y;
    a[x] = y*y;
  }

It also minimises the risk of doing something else wrong while 
editing - you can delete a statement without having to delete the
braces as well (and seveal times I've deleted one line too many).

(Auto-indenters don't help when it's C++ instead of C, they break.
Unless the GNU people have upgraded indent recently, but from what
I heard they weren't interested because the 'official' language
of GNU is C.)
