Change admonish(NULL, "foo") to inform("foo, continuing...").

Change admonish(NULL, "foo") to inform("foo, continuing...").

Removes more uses of the ad... functions with unneeded parameters.
Puts the "continuing" at the call site rather than the reader having to
remember it's being magically appended.  (Some calls were passing
"foo\n" that would result in "foo\n, continuing...\n" appearing.)
