You are right.  Shift-selection should be supported in WDired by this patch.

BTW, do you think that in WDired it would be more useful to select
rectangular regions because file names are organized in columns.
Then, for example, ‘downcase-region’ and ‘upcase-region’ will work
on the selected regions, not fail are they do now in WDired.
