Allow optional OSC 52 parameter

Browse Source 
Quoting from the XTerm documentation:

The first, Pc, may contain zero or more characters from the set c, p, q,
s, 0, 1, 2, 3, 4, 5, 6, and 7. It is used to construct a list of
selection parameters for clipboard, primary, secondary, select, or
cut-buffers 0 through 7 respectively, in the order given. If the
parameter is empty, xterm uses s 0 , to specify the configurable
primary/clipboard selection and cut-buffer 0.
