[Plugin: Remove slug from custom post type] Last character stripped when using suffix

Hi, I got the last character stripped when using a suffix.

So, if we have a slug something and a suffix html, we end up with an url like somethin.html.

I’m using /%postname%.html globally.

I hope this can be solved changing line 124 and 125 of file remove-slug-custom-post-type.php:
if (!empty($suffix)) $permalink = substr($permalink, 0, -1) . ".{$suffix}";

To:

if( !empty($suffix) )
if( substr($permalink, -1) == '/' )
$permalink = substr($permalink, 0, -1) .'.'. $suffix;
else $permalink = $permalink .'.'. $suffix;

Best. ??
