Re: gnus-carpal-mode and mouse-autoselect-window

[Richard Stallman]

    If marker M points to position P in buffer A and you're in buffer B,
    (goto-char M) will go to position P in buffer B, ignoring the fact that M is
    a position in buffer A and that P may be outside of point-min...point-max in
    buffer B.

Point can't move to a position outside the accessible part of the
buffer.  If P is outside the accessible part, it gets brought within
the accessible part, just as it would be if you specified it as an
integer.

I will clarify that fully in the manual.  Thanks to both of you for
showing me this part was not clear.
