Sorry, no.  I was misunderstanding completely --- I thought your error
was that spaces were wrong in the line that was being output.

As Mikael says, it's certainly not the case that preexec is supposed to
veto lines based on the history.  It's purpose is unrelated to the
recording of history: it's there to pass information about the line
about to be executed.
