Why inserting extra characters after wrapping?

[pedrormjunior]

I have noticed that after wrapping, this code is inserting some characters by calling the function ansi_terminate_lines. As it is disturbing the behavior I would expect, I would like to know why this function is being called at the end of the wrap function.

ansiwrap/ansiwrap/core.py

Line 92 in 20e2e8c

return ansi_terminate_lines(wrapped)

My situation is the following: I have a string s with multiple lines (i.e., multiple '\n') with lots of ANSI code all along. When calling ansiwrap.fill(s, replace_whitespace=False), it does not work properly, as it is breaking the line before the width although the next word in the following line would fill properly in the same line.

Then I decided to split s as s.split('\n') and apply ansiwrap.fill(line) as x = [ansiwrap.fill(line, width=columns) for line in s.split('\n')] for joining the result later: s = '\n'.join(x).

In this case, however, some ANSI code in the previous line that should affect the next line is not affecting anymore. By removing the ansi_terminate_lines it works fine for me.

Thank you for the initiative!
