    with-editor-export-editor: Use printf instead of echo
    
    The `-e' flag of `echo' that makes the command interpret
    backslash-escaped sequences (in particular "\037") is not supported
    in all shells.
    
    Shells that do not support it print the flag instead.
    
    So here we replace `echo' by `printf' which seems to be better
    supported and does the interpretation of backslash-escaped sequence
    by default.
    
    Re #71.
    Closes #72.
