Strange entrys in exclude field

Hi,

as i checked Autoptimize in an Developer WP-Installation i found these strange entrys in the exclude list:

s_sid, smowtion_size, sc_project, WAU_, wau_add, comment-form-quicktags, edToolbar, ch_client, nonce

I’se searched all files (and inside the files) of the WP-Installation but couldn’t find any trace of these scripts.

Does anybody know, if these entrys in the exclude list are really necessary and / or to which plugin they belong or what they are good for?

Big thx in advance to the communinity and of course Frank Gossens ??
