Doh!  I found my problem.  Either commenting out

#fconfigure stdin -encoding utf-8 -translation ~a
#fconfigure stdout -encoding utf-8

or enabling (setf translation "crlf") fixes all my problems.  Why I didn't
see this earlier?  Why did I let the :lispworks scare me away?

The Ltk examples and ABLE both work fine now.

A major benefit of the (sleep 1) was to let Tk appear before Ltk sent it
bad commands.  However, it should not be removed; I still need it for
proper operation under clisp.

By my understanding, SBCL is the only lisp that doesn't translate ~% as
\r\n on MS platforms.  Thus every other CL on windows should get the crlf

Here are my recommended patches to the current repl/ltk.lisp.  With them,
Ltk::ltktest and ABLE::start ran properly under both clozure-1.4 and
clisp-2.48.  Note that Clozure puts :windows on *features*, and Clisp uses
