### Description / Steps to reproduce the issue
Hello folks!
Seems some changes on NSH have absolutely obliterated Espressif's internal
CI.
I have traced the issue using git bisect to the following commit:
- `893f0c31eed10adf58ca95b52fffed56f89e43c5` (`readline: remove 5x
duplicated in redraw code`)
- PR #3657
The issue is that `pytest-embedded-nuttx` is parsing the command line and
fails to match the regex for the `echo $?` command.
Analyzing the serial output as received by the tool we have this:
- Issues commands:
- ls /dev
- echo $?
- Before the changes
```
nsh> #x1B[Kls /dev
/dev:
console
null
random
ttyS0
zero
nsh> #x1B[K
nsh> #x1B[Kecho $?
0
nsh> #x1B[K
```
- After the changes:
```
nsh> #x1B[Kl#x1B[Ks#x1B[K #x1B[K/#x1B[Kd#x1B[Ke#x1B[Kv#x1B[K
/dev:
console
null
random
ttyS0
zero
nsh> #x1B[K
nsh> #x1B[Ke#x1B[Kc#x1B[Kh#x1B[Ko#x1B[K #x1B[K$#x1B[K?#x1B[K
0
nsh> #x1B[K
```
I´m not aware if those are ANSI or UTF-something escape values, but seems
there is a symbol repeating before each character that is passed to the serial
output (#x1B[K).
Please if someone can check and confirm if that is expected. If so, how
should we parse it?
Thanks in advance.
