OK, the fix for this is easy.
I added double-quotes around the filename for Esc e in ed.ex.
(.ex and .exw files).
I changed ed.ex (line 1795) to read:

if platform() = LINUX then
    shell("exu " & file_name)
elsif match(".exw", lower(file_name)) or
      match(".ew",  lower(file_name)) then
    shell("exw \"" & file_name & "\"")  
else
    shell("ex \"" & file_name &"\"")
end if

I'll test the double-quote fix on Linux later today
and check in the change.
