Fix up the busted OSC command list (reset palette and
set palette). Remove CSI prefix from the list of non-CSI
escapes. End all items of said list with periods,
matching other sections of the page.

As I understand it, it's there because CSI is not a CSI-prefixed 
sequence (i.e., you have to first document CSI itself, and then in a 
different list you can document sequences prefixed by CSI).
So I'd say it belongs there.

Regarding this, I don't know what the intention of the original author was.

The pre-git code was (man-pages-1.70):

```
ESC ( U		\0\0\0Select null mapping \- straight to character ROM
ESC ( K		\0\0\0Select user mapping \- the map that is loaded by
		\0\0\0the utility \fBmapscrn\fP(8).
ESC )		Start sequence defining G1
		(followed by one of B, 0, U, K, as above).
ESC >	DECPNM	Set numeric keypad mode
ESC =	DECPAM	Set application keypad mode
ESC ]	OSC	(Should be: Operating system command)
		ESC ] P \fInrrggbb\fP: set palette, with parameter
		given in 7 hexadecimal digits after the final P :-(.
		Here \fIn\fP is the color (0-15), and \fIrrggbb\fP indicates
		the red/green/blue values (0-255).
		ESC ] R: reset palette
.TE
.SS "ECMA-48 CSI sequences"
```

Maybe it should go into a separate subsection called "Operating system 
commands"?


Thanks,

Alex
