Dec-digit-char-listp-results

Theorems about results of std/strings functions that return lists of decimal digit characters.

Those std/strings are accompanied by theorems that they return dec-digit-char-list*p, but they in fact return true lists, so here we add theorems that they return dec-digit-char-listp.
