Summary: break points mess up dynamic environments

Initial Comment:
SISC (1.13.2-rc)
#;> (import string-io)
#;> (define (foo) (display "bar"))
#;> (with-output-to-string foo) ;returns "bar", as expected
"bar"
#;> (import debugging)
#;> (set-breakpoint! 'foo)
#;> (with-output-to-string foo) ;;instead of the breakpoint message, *nothing* 
gets displayed
#;> (continue) ;;displays bar and returns breakpoint message, which is wrong
bar"{break: (foo)\n ?:?:?: <indeterminate call>\n}\n"

It's pretty obvious why this is happening, looking at the implementation of 
set-breakpoint!.
