OS Ubuntu 22.04.5 LTS, liedit installed from apt:
```
libedit-dev/jammy,now 3.1-20210910-1build1 arm64 [installed]
libedit2/jammy,now 3.1-20210910-1build1 arm64 [installed,automatic]
```
I expect that searching history in lldb would work as it does in my terminal:
* `ctrl+r` enters `(reverse-i-search)`':`
* I start searching and find the command I want
* I want to edit that command before running, so I press an arrow key, usually right
* That exits the search mode and leaves the cursor one to the right of where it was
```
$
<ctrl-r>
(reverse-i-search)`':
<nin>
(reverse-i-search)`ninj': ninja
<right arrow>
$ ninja
```
When you do this in LLDB it exits the mode but the raw character code is inserted for right arrow, instead of making the cursor move:
```
(lldb) watchpoint set variable a
bck:set
<right arrow>
(lldb) watchpoint [Cset variable a
```
That `[C` is actually there it's not just a visual artifact:
```
(lldb) watchpoint [Cset variable a
"[Cset" is not a valid subcommand of "watchpoint". Valid subcommands are: command, delete, disable, enable, ignore, and others. Use "help watchpoint" to find out more.
```
We know that we should exit but not that it needs to be handled as a special character.
