feat: defaults: auto-create backup dir

Browse Source 
Copy the behavior of 'undodir' and create the last specified directory
in the 'backupdir' option if it doesn't exist.

Use trailing slashes for 'backupdir' as well as 'viewdir' and 'undodir'
by default. Note that 'undodir' always behaves as though it has the
trailing slashes, regardless of whether or not they are present. They
are added to the default option value to minimize surprise.

The '.' value in 'backupdir' is kept because the default behavior for
backups is solely to have a backup if the save of the main file to disk
fails. As soon as that save is completed the backup file is removed, so
generally there is no need to put them in a central location.
