I know it seems obvious what this does, but add a sentence at least, and a
short example. Like:
```
The `%undo` command reverts the last input.
clang-repl> int a = 1; a
(int) 1
clang-repl> %undo
clang-repl> a
In file included from <<< inputs >>>:1:
input_line_2:1:1: error: use of undeclared identifier 'a'
1 | a
| ^
error: Parsing failed.
```
This one just shows that a can be printed before the undo, but not after.
