patch 8.0.0015

Browse Source 
Problem:    Can't tell which part of a channel has "buffered" status.
Solution:   Add an optional argument to ch_status().  Let ch_info() also
            return "buffered" for out_status and err_status.

"buffered" is used when the channel was closed but there is
still data that can be obtained with |ch_read()|.
If {options} is given it can contain a "part" entry to specify
the part of the channel to return the status for: "out" or
"err". For example, to get the error status: >
ch_status(job, {"part": "err"})
