Shell prompt output

[Rachid Koucha]

Hi,

Using busybox 1.34.1, I noticed that ash shell displays the prompt on
stdout instead of stderr when CONFIG_FEATURE_EDITING is set. Other shells
like bash do not behave this way: the prompt is always on stderr.

Moreover, the IEEE standard specifies that the prompt must be written on
stderr:

*PS1* Each time an interactive shell is ready to read a command, the value
of this variable shall be subjected to parameter expansion and written to
standard error.


Regards,

Rachid
