Problem: When reading channel output in a timer, messages may go missing.
(Skywind)
Solution: Add the "drop" option. Write error messages in the channel log.
Don't have ch_canread() check for the channel being open.
Problem: When using ch_read() with zero timeout, can't tell the difference
between reading an empty line and nothing available.
Solution: Add ch_canread().
Problem: Popup menu always appears above the cursor when it is in the lower
half of the screen. (Matt Gardner)
Solution: Compute the available space better. (Hirohito Higashi,
closes#1241)
Problem: When a channel callback consumes a lot of time Vim becomes
unresponsive. (skywind)
Solution: Bail out of checking channel readahead after 100 msec.
Problem: When the input or output is not a tty Vim appears to hang.
Solution: Add the --ttyfail argument. Also add the "ttyin" and "ttyout"
features to be able to check in Vim script.
Problem: C indenting does not support nested namespaces that C++ 17 has.
Solution: Add check that passes double colon inside a name. (Pauli, closes
#1214)

Problem: When the channel callback gets job info the job may already have
been deleted. (lifepillar)
Solution: Do not delete the job when the channel is still useful. (ichizok,
closes#1242, closes#1245)
Problem: Cannot make Vim fail on an internal error.
Solution: Add IEMSG() and IEMSG2(). (Domenique Pelle) Avoid reporting an
internal error without mentioning where.
Problem: Exit value from a shell command is wrong. (Hexchain Tong)
Solution: Do not check for ended jobs while waiting for a shell command.
(ichizok, closes#1196)
Problem: Checking did_throw after executing autocommands is wrong. (Daniel
Hahler)
Solution: Call aborting() instead, and only when autocommands were executed.
Problem: when calling an operator function when 'linebreak' is set, it is
internally reset before calling the operator function.
Solution: Restore 'linebreak' before calling op_function(). (Christian
Brabandt)
Problem: When using an Ex command for 'keywordprg' it is escaped as with a
shell command. (Romain Lafourcade)
Solution: Escape for an Ex command. (closes#1175)
