Subject: o acl_from_text.c:   - errno is already set to ENOMEM (as
 appropriate) when asprintf(),     strdup(), or acl_init() fails o
 acl_to_text.c:   - the return value of the initial strdup() is not checked  
 - errno is already set to ENOMEM (as appropriate) when asprintf     and
 acl_init() fails   - let the the default: case use 'goto error_label' for
 consistency
