source            -> html output
================================
Begin_Html        -> "<pre>"
Begin_Html <pre>  -> "<pre>"
Begin_Html </pre> -> "<pre></pre>"

(and accordingly for End_Html). The exact behavior:
THtml keeps track of whether there is an open <pre> (e.g. due to Begin_Html)
or not. If there is an open <pre> all other opening <pre>s will be ignored,
only closing </pre>s will be accepted. This allows code like in TMinuit,
where </pre> is closed directly after Begin_Html, but where there are other
<pre>...</pre> code blocks inside the same Begin/End_Html block. This
"algorithm" is far from perfect, but it should work for simple cases.

THtml's code is not getting any nicer (yak: yet another kluge); Christian
Holm Christensen and I are planning / working on a complete rewrite of
THtml. For me it's a spare time project, so it might take a while. Until
then, provided rootdev decides to apply this patch, this is what THtml does
to pres in Begin/End_Html blocks.
