Ok, so I agree with you that put_line features are a good thing, but I
don't think they solve the whole problem.

For example if you want to set a multi-line message in a message box,
you can use one of the following :

1) 

msg_box.set_msg(error_header + eol + error_msg + eol + help_msg)

2)

msg_box.set_msg(error_header + "%N" + error_msg + "%N" + help_msg)

3)

my_msg.append_line(error_header)
my_msg.append_line(error_msg)
my_msg.append_string(help_msg)
msg_box.set_msg(my_msg)


From this example you can see that 1) is both very short and likely to
be portable, while 2) is not likely to be portable and 3) is not short.

Christian.
