Except that as soon as your code has tabs in it, all bets are off for aligning
anything. A tab is a variable-width character and is incompatible with
the notion of monospace alignment. It might seem to work so long as you
always view it in the same editor with the same tab width, but it'll surely
break as soon as someone views it with a different tab width.
