patch 8.0.0860: side effects when channel appends to a buffer
Problem: There may be side effects when a channel appends to a buffer that
is not the current buffer.
Solution: Properly switch to another buffer before appending. (Yasuhiro
Matsumoto, closes #1926, closes #1937)

| 12 * NetBeans Debugging Tools. What are these tools and why are they important? | |
| 13 * There are two main tools here. The first tool is a tool for delaying or | |
| 14 * stopping gvim during startup. The second tool is a protocol log tool. | |
| 15 * | |
| 16 * The startup delay tool is called nbdebug_wait(). This is very important for | |
| 17 * debugging startup problems because gvim will be started automatically from | |
| 18 * netbeans and cannot be run directly from a debugger. The only way to debug | |
| 19 * a gvim started by netbeans is by attaching a debugger to it. Without this | |
| 4352 | 20 * tool all startup code will have completed before you can get the pid and |
| 7 | 21 * attach. |
| 22 * | |
| 23 * The second tool is a log tool. | |
| 24 * | |
| 25 * This code must have NBDEBUG defined for it to be compiled into vim/gvim. | |
