[Bug-apl] Quad-quote doesn't echo on dumped files

[Blake McBride]

If I dump a file with quad-LX set, quad-quote doesn't echo.  It does if I
save the file instead of dump though.   e.g.:


      )CLEAR
CLEAR WS
      ∇start;x
[1] x←⍞
[2] ∇
      ⎕LX←'start'
      )SAVE s1
2015-10-18  19:50:23 (GMT-5)
      )DUMP d1
2015-10-18 19:50:31 (GMT-5)
      )LOAD s1
SAVED 2015-10-18 19:50:23 (GMT-5)
aaaaa
      )LOAD d1
DUMPED 2015-10-19 00:50:45 (GMT-5)


s1 echoed the 'aaaaa' that I typed.  d1 did not!  (Having dump files
support ⎕LX is a very good thing IMO.)

Thanks.
