Summary: BR within PRE rendered with additional linefeeds

Initial Comment:
Sometimes in the wild there is HTML code with PRE sections containing BR tags instead of linefeeds, like so:

<pre>first line<br>second line<br>third line</pre>

JTidy's pretty-printer renders it like this ("break-before-br" is false):

<pre>
first line<br>
second line<br>
third line
</pre>

The result is that a browser renders two linefeeds where just one should exist, causing ugly empty lines in the output. The problem gets worse if for some reason I use multiple passes of JTidy, adding more and more linefeeds.

How to fix: never ever add newlines after BR tags inside PRE sections.

Message:
I just uploaded my humble try to fix the problem. Maybe it is a bit hacky
and not the optimal solution, sorry this was my first look into your code
and I have not been programming for a while. But at least locally it solves
my problem and might be potentially beneficiary for other users, too.
