[U-Boot] [BUG] cmd : Local Hush Variable Could not be deleted

[Adarsh Babu Kalepalli]

Hi,

+ u-boot version:2019.10
+ H/W Board : Beaglebone Black

With 'localvar=' at the shell prompt
, I tried to delete a existing Hush-shell local variable.


-----------------------------------------------------
=> localvar=hello
=> showvar
HUSH_VERSION=0.01
target=pxe
devnum=1
localvar=hello
=> localvar=
=> showvar
HUSH_VERSION=0.01
target=pxe
devnum=1
localvar=hello
------------------------------------------------------

The 'localvar' still exists and is not deleted.
How do I delete a hush-shell local variable??
