patch 7.4.2344

Browse Source 
Problem:    The "Reading from channel output..." message can be unwanted.
            Appending to a buffer leaves an empty first line behind.
Solution:   Add the "out_msg" and "err_msg" options. Writing the first line
            overwrites the first, empty line.

For a new buffer 'buftype' is set to "nofile" and 'bufhidden' to "hide". If
you prefer other settings, create the buffer first and pass the buffer number.
*out_modifiable* *err_modifiable*
The "out_modifiable" and "err_modifiable" options can be used to set the
'modifiable' option off, or write to a buffer that has 'modifiable' off. That
means that lines will be appended to the buffer, but the user can't easily
change the buffer.
*out_msg* *err_msg*
The "out_msg" option can be used to specify whether a new buffer will have the
first line set to "Reading from channel output...". The default is to add the
message. "err_msg" does the same for channel error.
'modifiable' option off, or write to a buffer that has 'modifiable' off. That
means that lines will be appended to the buffer, but the user can't easily
