Hi,
what is the correct way to clear a local variable in the hush shell? The
"c=" doesn't work because the commit "common: cli_hush: avoid dead code"
(aa722529635c16c52d9d609122fecc96ec8d03e4) explicitly change the
function set_local_var to return -1 if a value is missing.
Regards
Stefan

I don't see how that changed anything, but perhaps there is a case I am missing.
Can you send a patch to fix it? It seems like a bug.
