    driver-gl: re-indent misleading if-else statement
    
    There was a very, very, very misleading if else statement using no
    braces for a single statement if block, followed by a blank line *and*
    followed by a comment before the else which was aligned to the 'if'
    column, all leading you to believe on first glance that there is no else
    block. The fact that Neil and I were both separately mislead by this,
    this week, is a pretty compelling reason to clarify this by deleting the
    blank line, and moving the comment inside the else block.
