-Subject: [PATCH] ash: fix a regression in handling local variables
-
-commit 109ee5d33694a03cda3424b4846584250832ba8e
-"ash: make "locak VAR" unset VAR (bash does that)"
-
-This commit introduced a regression where calling local on an already
-local variable unsets it. This does not match bash behavior.
-
-Update test case to check for this behavior
