Make truncated link better

Hi

I use plugin “Auto-hyperlink URLs” 4.0 for WordPress. In Settings I use truncate function with 30 characters

Original url:

http://domain1.com/111111111111111111111/this_this_long_file_name.part001.rar.html
http://domain1.com/222222222222222222222/this_this_long_file_name.part002.rar.html

http://domain2.com/111111111111111111111/this_this_long_file_name.part001.rar
http://domain2.com/222222222222222222222/this_this_long_file_name.part002.rar

After:

http://domain1.com/111111111111111…
http://domain1.com/222222222222222…

http://domain2.com/aaaaaaaaaaaaaaa…
http://domain2.com/bbbbbbbbbbbbbbb…

But I prefer if looking like this:

http://domain1.com/111111111111111…part001.rar.html
http://domain1.com/222222222222222…part002.rar.html

http://domain2.com/aaaaaaaaaaaaaaa…part001.rar
http://domain2.com/bbbbbbbbbbbbbbb…part002.rar

Meaning keep from partXX…. to end.

Please update in new version
