Wrong description of 'protected@cseappto' and 'protected@csxappto' in the manual

[dr-scsi]

I'm not really familiar with the code of etoolbox but I think the following line in the manual https://github.com/josephwright/etoolbox/blob/3552e3d9b96d5b95e25d08f1772f47b7b72cd604/etoolbox.tex#L406 should read

\cmditem{protected@cseappto}{csname}{code}

and this one https://github.com/josephwright/etoolbox/blob/3552e3d9b96d5b95e25d08f1772f47b7b72cd604/etoolbox.tex#L410 should be

\cmditem{protected@csxappto}{csname}{code}
