In order to find an appropriate browser function for the given
kind, first the browser handler lists are consulted.  If no
handler is found, the `browse-url-browser-function',
`browse-url-secondary-browser-function`,
`browse-url-default-browser' and `eww' are tried in that order
until a browser function with a matching kind is found.  This
way the user customization of `browse-url-browser-function' and
`browse-url-secondary-browser-function` is respected by
`browse-url-with-browser-kind'.
