The problem is when it encounters a '<'
character, that is *not* followed by a
valid tag start, according to istagstart()

Such as: < CODE >, and similar constructs.

Then it fails to advance the pointer (!),
and keeps on scanning the '<' character
forever. Inserting a "else p++;" works...

You still need <code> and </code> in order
for D to actually parse the code, but at
least it comes back again with this patch.

Thanks!  I don't think "< CODE >" is valid HTML, so this patch should be enough.

I've run the attached file (with "< code>" and "</ code>")through the validator at http://validator.w3.org/check

An got no warnings or errors.

If you validate as XHTML, instead of the old HTML 4.0,
you get the following validation errors (from same w3):

In general, XHTML and UTF-8 are now recommended
instead of the old HTML 4.01 and ISO-8859-1...


Anyway, nobody writes < code > in any real stuff.
It's just that it's nice if D doesn't HANG on it. :-)
