I went ahead and fixed this along with a bunch of other warnings
revealed by the test (that has snuck in after Rober fixed the last batch,
I think).

There's some that are rather intractable, though, like
sql-postgres-login-params.

These remain:

whitespace-indentation-regexp
whitespace-space-after-tab-regexp
sql-postgres-login-params
gdb-display-source-buffer-action

I don't quite understand what's wrong here:

(defcustom whitespace-indentation-regexp
  '("^\t*\\(\\( \\{%d\\}\\)+\\)[^\n\t]"
    . "^ *\\(\t+\\)[^\n]")
[...]
  :type '(cons (regexp :tag "Indentation SPACEs")
	       (regexp :tag "Indentation TABs"))
  :group 'whitespace)

Isn't that how you specify a cons of two values?
