cope with multiple line breaks within sideband progress messages

Browse Source 
A single sideband packet may sometimes contain multiple lines of progress
messages, but we prepend "remote: " only to the whole buffer which creates
a messed up display in that case.  Make sure that the "remote: " prefix
is applied to every remote lines.
