bug#6741: 24.0.50; ansi-term: spurious newlines (soft linebreaks becomes had linebreak)

[Sébastien Gross]

Hi,


I am currently using ansi-term as a terminal emulator. the problem is
when lines are longer than the buffer column number a hard newline
('\n') is inserted.
Thus when some text is copied (with using both the mouse or keyboard
sequences) some spurious new line appear into the pasted text.

For example in ansi-term type:

echo "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod 
tempor in cididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, 
quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo 
consequat."

(this line is intentionally left long)


If you try to copy/past  it (using the mouse selection and middle click)
you might get something like (depending on term-window-width):


echo "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiu
smod tempor in cididunt ut labore et dolore magna aliqua. Ut enim ad minim 
veniam, quis n
ostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat."

As you can see hard newline appear.


Is there a way to fix this ?

Thanks in advance.

Regards
