patch 8.0.0863: a remote command does not work in the terminal window

Problem:    A remote command starting with CTRL-\ CTRL-N does not work in the
            terminal window. (Christian J. Robinson)
Solution:   Use CTRL-\ CTRL-N as a prefix or a Normal mode command.

+The special key combination CTRL-\ CTRL-N can be used to prefix one Normal
+mode command.  This is especially useful for remote commands, when you don't
+know whether Vim currently has focus in a terminal window.  Note that only one
+Normal mode command can be used.

 In Terminal mode the statusline and window title show "(Terminal)".  If the
 job ends while in Terminal mode this changes to "(Terminal-finished)".
 
+Environment variables are used to pass information to the running job:
+    TERM		name of the terminal, 'term'
+    ROWS		number of rows in the terminal initially
+    LINES		same as ROWS
+    COLUMNS		number of columns in the terminal initially
+    COLORS		number of colors, 't_Co' (256*256*256 in the GUI)
+    VIM_SERVERNAME	v:servername
+
+The |client-server| feature can be used to communicate with the Vim instance
+where the job was started.  This only works when v:servername is not empty.
+If needed you can set it with: >
+	call remote_startserver('vim-server')
+
+In the job you can then do something like: >
+	vim --servername $VIM_SERVERNAME --remote +123 some_file.c
+This will open the file "some_file.c" and put the cursor on line 123.
