[Libssh] channel_read - Save read characters in "string"

[Rico Kerster]

Ah just noticed something.
I execute the "ls" command (directory with a few hundred files), and I just get 1024 characters, the rest gets cut. buffer_new() seems to allocate just 1024 Bytes. Is there any way to store more than 1024 bytes?

Thanks in advance
Kind regards
Rico Kerster
