Subject: [9fans] patch: serial mouse middle button emulation

Code is present in /sys/src/9/port/devmouse.c to support middle button
emulation for serial mice, but the "mouseshifted" variable is never set.
Adding 3 lines to /sys/src/9/pc/kbd.c (marked with "+" below) fixes the
problem:

/sys/src/9/pc/kbd.c
----
static Lock i8042lock;
static uchar ccc;
static void (*auxputc)(int, int);
+ extern int mouseshifted;
----
  case Shift:
   shift = 0;
+   mouseshifted = 0;
   break;
----
  case Shift:
   shift = 1;
+   mouseshifted = 1;
   return;
----
