there is a bug in HUSH's handling of "if" / "elif" commands:
$ if true

$
The same bug exists in all versions of HUSH from BB v0.60.x up to and
including v1.00-pre9. The attached patch fixes this:
$ if true
> then
> echo 1
> elif
> true

> elif
> true
> then
> echo 3
> else
> echo 4
> fi
1
$
Best regards,
Wolfgang Denk
