Patch 8.2.4685
Problem: When a swap file is found for a popup there is no dialog and the
buffer is loaded anyway.
Solution: Silently load the buffer read-only. (closes #10073)

'buftype' set to "popup". That buffer will be wiped out once
the popup closes.
+ if {what} is a buffer number and loading the buffer runs into
+ an existing swap file, it is silently opened read-only, as if
+ a |SwapExists| autocommand had set |v:swapchoice| to 'o'.
+ This is because we assume the buffer is only used for viewing.
+
{options} is a dictionary with many possible entries.
See |popup_create-arguments| for details.
