Evaluating a pprint-logical-block form without the optional 'out'
keyword argument throws an exception.  (See details below.)  It works
fine when that is provided.

Based on a quick look at kawa/lib/kawa/pprint.scm, I suspect the
problem is just a missing (define out-expr #!null) in the
define-syntax-case.  The attached trivial patch seems to do the trick,
but I have not tested carefully.  (I can also submit using gitlab if
you prefer.)


I checked this in. Thanks!
