subst command in RPN mode (bug ?)

However, in RPN entry :

'2*Q' Enter
'Q=2' Enter
subst(2) Enter

The single quotes are lost when you press enter, on the stack you don't have '2*Q' but just 2*Q.
So you need to add another set of single quotes or double
quotes around the parameters to make it work , for example :

"'2*Q'" Enter
"'(Q=2)'" Enter
subst(2)
