Well, the driver `nolinks' certainly has to define \@hlstart
to produce \leavevmode, otherwise `nolinks' will no longer
provide identical typesetting which is its only reason for
existence.

As for \hloff / \hlon, I think it will also be a good idea
to produce the \leavevmode even when links are (temporarily)
off.  Otherwise the following code (placed in vertical mode)
will give different results depending on what state we are
in:

  \hlstart{}{}{LABEL}
  Text of the link\hlend.

When \hloff (and therefore no \leavevmode) there will be no
space before `Text'; when \hlon (meaning \leavevmode) there
will be the space.  This is bound to confuse the user.
