But this means that continuous mode should be enabled by default,
because the current default behavior is a kind of continuous mode
that allows only SPC and DEL to jump to the next/previous page.

This means that users will be interested only in changing the value of
`doc-view-continuous-kind' (interactively from the menu or with a command
bound to some key).  Thus the minor mode `doc-view-continuous-mode'
will be useless.
