`C-x =' shows information about the current position, including its
relation to the buffer size, its column, the region limits, and
horizontal scroll amount.
That position info is missing from the *Help* display for `C-u C-x ='.
It is only shown in the message, which is ephemeral and can easily be
overwritten.
The attached patch remedies this by including the position information
in *Help*. The patch also updates the doc string accordingly (and
corrects improper grammar such as "Is POS is taken...").
