Subject: [PATCH] sh: Add test for assignment errors (e.g. trying to change a
 readonly var). We currently ignore readonly status for assignments before
 regular builtins and external programs (these assignments are not persistent
 anyway), so just check that the readonly variable really is not changed. The
 test depends on the command builtin changes for 'command :'.
