Hi Bastian,

the wording in the FreeBSD version of "man sh" is the most clear one (s. [1]):

     The only special parameter that can be made local is `-'. Making `-'
     local causes any shell options that are changed via the set command
     inside the function to be restored to their original values when the
     function returns.

Best regards,
Gene
