The patch permits to insert a single space character in a `character'
field, something which was not allowed before.  The error you see comes
from the `\n' on the next line.  Replace the "\n" by a "\t" and the
error should disappear.

It's not easy to resolve the "\n" problem since wid-edit creates two
overlays when a newline character is last in an editable field.  I'll
try to look at that eventually.  Is the following inacceptable?

(defcustom rs-test-list-string
   '("<body[^>]*>"
     (("&"   . "&amp;")
      (" "   . "&nbsp;")
      ("\n"  . "<br>")
      ))
   "List for inserting mail headers into the HTML output."
   :type '(choice
           (list :tag "Default"
                 (regexp :tag "Body regexp" "<body[^>]*>")
                 (repeat :value (("&"   . "&amp;")
                                 (" "   . "&nbsp;")
                                 ("\n"  . "<br>"))
                         (cons (string) (string :tag "Replacement"))))))
