what-cursor-position - why not list the line # as well?

[Drew Adams]

`what-cursor-position' gives lots of info about the cursor position,
including the column:

 Char: d (100, #o144, #x64) point=298976 (99%) column=51

Why not have it also provide the line #? That way, people wouldn't need to
use `what-line' as well as `what-cursor-position' to get all the info (and
`what-line' is unbound in many buffers).
