That is horrible. Functions should do what their names say.
`count-lines-region' should count the lines in the region. Period. Is
this so difficult to grasp?
How about renaming the above function `count-lines' and defining
`count-lines-region' properly.
Some of us don't use transient-mark-mode.

I think it is more about naming than functionality. It seems (up to) six
functions are called for: `count-{lines,words}-{,region,buffer}'. With
this approach, the above problem evaporates.

"wc", like the raiser of bug #9429 suggested. But please, please, please,
if the function has "region" in its name, make it work on the region.
