Pressing keypad 5 (while numlock is off) on the linux console or on xterm makes mc stop reading the input for a second or two.

Cause: unrecognized escape sequence - mc tries to read (using timed reads) until the sequence is over.

Proposed solution: teach mc KP_5 (some sources call it KP_BEGIN or KP_CLEAR). I tried to add it in /usr/share/mc/mc.lib but that didn't work. Sequence on the Linux console on PC:
e[G and on xterm:

As a test I applied the patch attached - it is probably not the proper solution but fixed the problem for me on the console.

mc version affected: 4.8.15, 4.8.17; I think this problem was not present in the 4.7 series.
