Re: something like linum.el ought to be added

[Juanma Barranquero]

Could I suggest also passing to the linum-format function (if any) the
total number of lines in the buffer (or the visible region)?

`linum-update-window' only needs to compute it once, while the
linum-format function is called for each line and would have to do
convoluted things to cache it (and somehow detect buffer changes).
