Patch 8.0.0015
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

+ "err". For example, to get the error status: >
+ ch_status(job, {"part": "err"})

*copy()*
copy({expr}) Make a copy of {expr}. For Numbers and Strings this isn't
different from using {expr} directly.
