getpos fix (trunk only)

     This ought to fix the problem excountered by Ken, where the cursor
wasn't at the spot '/y' was reporting on.  This reverses part of a change
from May, 2005.  I still don't understand the original behavior, which
was that docrt() for ^R followed by positioning the cursor at a specific
map coordinate and calling flush_screen() was leaving the cursor at the
end of the second status line.  Reversing flush_screen and curs(WIN_MAP)
made it work for tty but screwed up X11.  It turns out that including
pline("Move cursor to %s:") *also* makes things work as intended, so that
the flush/position hack wasn't necessary once that other change went in
(same 2005 patch, but the cursor hack was implemented first at that time;
once this reversal is in place, commenting out the pline() does bring the
odd behavior for tty back).
