[tex4ht] How to insert HTML code at any location in the generated HTML file?

[Karl Berry]

    Runaway argument?

I see CVR solved your problem with an environment.  That's good (maybe
we should add that environment in general), but this error indicates the
problem is simply having a blank line (\par) in the argument, and we
should just make \HCode \long in order to allow it.  (I admit I didn't
actually check if something weirder is going on.)

CVR, wdyt?
