Unclear edge situation

[buhtz]

First I thought that codespell isn't able to handle newlines but it is. This gives no error:

$ echo exist\nin | codespell -

But this gives me an error:

$ echo "exist\nin" | codespell -
1: exist\nin
        nin ==> inn, min, bin, nine

Do you have an idea why it is that way?

I experienced that problem in my production code. The original line can be found here

Codespell is not able to handle “newlines” the way you think it might. See #17.

This is actually a shell question, not a codespell question, and it has nothing to do with newlines:

$ echo exist\nin
existnin
$ 
$ echo "exist\nin"
exist\nin
$ 
$ echo exist\\nin
exist\nin
$

Have a look at #1774 (comment).
