2 bugs in posn-at-x-y on a tty

[Nick Roberts]

There appear to be two bugs posn-at-x-y when used in an tty:

1) On the mode-line the string returned is one located one character to the
left of the x co-ordinate (starts from one but should really start from zero?).
So clicking on the colon of the mode-line in an xterm returns the buffer
coding system rather than changing the eol style.

2) The margin is not recognised. If the left-margin is 2 characters wide then
I think that x=0, y=10 should be recognised as being in the margin
(POS-OR-AREA should be 'left-margin and not nil) and true window co-ordinates
should start a 2.
