Is there a way to customize my modeline such that I can see the total number of
lines of the current file?
The percentage is not particularly interesting to me...
Thanks!

I use these forms in my `mode-line-format' variable to show "current_line/total_num_lines":
(list 'line-number-mode " L%l/")
(list 'line-number-mode (:eval (int-to-string (count-lines (point-min) (point-max)))))

Note that this method will be affected by narrowing. To get the full
number of lines in the buffer use (1+ (count-lines 1 (buffer-size))).
This could also get rather sluggish when used in large buffers. The
best way would probably be to use a timer to recalculate the number of
lines in the buffer and then use that.

You bet! The default method has some clever wizardry in the display
engine to not count too many lines unless necessary. If we want to
support N/M display, we should make it part of the display engine, to
avoid re-counting each time redisplay is entered. Patches are welcome.
