I think this is a slightly better solution:
:function Count_words() range
: let lnum = a:firstline
: let n = 0
: while lnum <= a:lastline
: let n = n + len(split(getline(lnum)))
: let lnum = lnum + 1
: endwhile
: echo "found " . n . " words"
:endfunction
It counts white space separated words, but that shouldn't matter in this
context.

I'll move it to there.
