Thats not really what i meant, i was wondering if an ftp server ever
sends linewrapped text, but it doesn't look so. However, you're right
that the filenames can contain '\n'. I just tried with a local ftp
server, and it handed me this:
---------x 1 500 500 0 Oct 20 07:16 a
b
drwxrwxr-x 2 500 500 4096 Oct 20 07:13 a really really long
name, a really really long name,a really really long name,a really really long
name,a really really long name,a really really long name,a really really long
name
-rw-rw-r-- 1 500 500 55 Oct 20 07:16 a.c
Where the first filename is "a\nb".
I'm not sure this is worth worrying about though, it seems pretty
unusual, and might be hard to fix with the current code.
Go ahead and commit your patch, it at least clearly does better than
what we have now.
