bug#47454: plist-put should have a version which accepts multiple properties

[scame]

Modifying plists could be much easier if multiple properties
were also accepted.

E.g. (plist-put PLIST PROP VAL ... )

or (plist-put PLIST (PROP VAL ....) )


Others also find this problematic:

https://emacs.stackexchange.com/questions/39473/how-to-modify-multiple-keys-in-a-plist

and the suggessted solutions are clumsy:

  (setq org-format-latex-options (plist-put org-format-latex-options :scale 
1.5))
  (setq org-format-latex-options (plist-put org-format-latex-options 
:foreground 'auto))

or

  (setq org-format-latex-options
      (plist-put (plist-put org-format-latex-options
                            :scale 1.5)
                 :foreground 'auto))


Making plist-put smarter to accept multiple values or adding an
other function which accepts them (e.g. plist-put-multiple)
could make using plists much more convenient.
