hush: Don't parse the contents of a dereferenced var
When a variable which contains a user-supplied value is dereferenced (e.g. to be echo'ed), make sure that the value is not further parsed by hush. Set the hush local variable "HUSH_NO_EVAL=1" to enable this behavior. Without this patch, a sequence like this occurs: Panda # env set my_user_string Bob\'s favorite device Panda # print my_user_string my_user_string=Bob's favorite device Panda # echo $my_user_string syntax error hush.c:3007 With this patch, it looks like this: Panda # HUSH_NO_EVAL=1 Panda # env set my_user_string Bob\'s favorite device Panda # print my_user_string my_user_string=Bob's favorite device Panda # echo $my_user_string Bob's favorite device Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
