This was almost the exact example I was playing with when I decided to start
this messy discussion. Also some paragraph examples. Both of the following
should mean the same:

some text<P>more text


some text
more text

The latter being commonly used. I realized that unless you could remove
surround new-lines in cases like this, the second paragraph would start
with a space. Similarly, you might find headings, or other things with
a space at the beginning.

Note that the method I proposed has the advantage of automatically dealing
with this (sort of). If the document was converted simply by adding a <P>
to the end of each line, then for such lines, I remove the newline but keep
the <P>. Then the code that deals with PRE sections can happily honor
both new-lines and <P> tags, thus making it compatible with either style.
