[l2h] Both \latex{} and \html{} blocks appear in images.tex

[Julius Smith]

I just noticed that (in l2h v2k.1beta (1.55)) the defs

	\latex{
	  latex-only block
	}

	\html{
	  html-only block
	}

appear in images.tex as

	\latex{
	  latex-only stuff
	}

	html-only stuff

As a result, both blocks are compiled when processing images.tex.
Is this a bug? (It seems to be causing me some trouble.)
I would expect only the \latex{} block to appear.

Thanks,
Julius
