$POSTMATCH and $PREMATCH are their use English names. When I see such
variables, they confuse the hell out of me. I am familiar with common
variables such as $_, @_, $@, $0, etc. but not with every obscure perl
variable out there. use English is considered a good way to make your code
more readable and maintinable.

That it gives you $POSTMATCH and $PREMATCH.

There was such a link in one of the pages and I had to fix it myself.
It occurs whenever an HTML tag is broken in the middle. Here's a test
case:

<h1>Examples</h1>
<div class="example">
BeginExampleHere
Hallelujah
<a
    href="hello">
    You
    </a>
EndExampleHere
</div>

I did not break anything. I'm sorry that I changed these obscure variables
into something more readable. I can change them back if you want. But I
think that use English; is considered a good idea. I always use it.
