bug#49605: 28.0.50; *Shortdoc buffer*: 'n', 'p' not working as expected

[Gregor Zattler <grfz@gmx.de>]

Dear emacs developers, I recently learned about shordoc.el

When testing it I realized that keys 'n', 'p', bound to
shortdoc-next and shortdoc-previous respectively do not move
point to the next or previous example in the buffer, but to
BoB and EoB respectively.

Thanks for your attention, Gregor
