It appears I figured it out, though not sure why this didn't work the day before.
Just added the 3rd line there to str_replace the dash in output.php
$ft = preg_replace('/\.([^0-9])/', ' $1', $ft);
$ft = str_replace('_', ' ', $ft);
$ft = str_replace('-', ' ', $ft);
$ft = ucwords($ft);
return trim($ft);
I had also made a slight change in admin.php to preg_replace (in the line that catches file versions) but I have since removed that without effecting the fix.
Was happy to get this to work because I've been pushing to have files named with dashes between words for SEO purposes.
