The typo in https://orgmode.org/worg/org-faq.html#mailto-links

browse-url~browser-function
----------^

Looking at 
https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=c4adfbae24d9
Allow for custom URL handlers in browse-url.
(included into Emacs-28)

I decided that it is consistent with

>    nil("mailto:srandby@gmail.com"; (nil))
>    browse-url--mailto("mailto:srandby@gmail.com"; nil)

when `browse-url-mailto-function' is set to nil. However docstring to 
this variable allows nil (perhaps there is really an Emacs bug). Now I 
am puzzled why setting `browse-url-mailto-function' to 
`browse-url-default-browser' does not help. I have no idea what should 
be suggested to users instead of nil.
