If you use highlight_string() to produce HTML formatted source, the output string replaces newlines with <br \>.

This is very ugly and unnecessary. 
Whitespace is an important part of code; readability is not an insignificant feature.
Instead, "\n" should be replaced with "<br \>\n", or "<br>\n", to be HTML compliant.

<?php
// $source_file includes line breaks
$source=join('',file($source_file));
$body=highlight_string ( $source, $return=TRUE);
// $body is a single line, without line breaks
?>

Current PHP doesn't add linefeed as reporter said. However, we do not have to 
change behavior as highlighted source is for browsers, not human. 

Left this report open, in case someone would like to change behavior.

So at the least this warrants a documentation update right?

I submitted the attached patch to php doc system for review.

How would one go about introducing a minor enhancement as described - just a pull request?  The change is trivial and I don't think it would have any BC implications.

The documentation for this was fixed, I believe the main reason for why this was never fixed or changed was that highlighted code was intended for <pre> HTML tags.
