It looks like it is.  The reason this shows up is that spell checking
simply sets a flag in the history mechanism that the line currently
being parsed isn't to be executed when it's finished.  However, I think
that if that flag is set there is no point in reporting any syntax
errors since the code isn't going to be executed.
