Subject: Trouble Counting Words, Sentences and Paragraphs

I'm working on the first example application from 'Learning Ruby, from
Novice to Professional,' a text analyzer that counts the number of
characters (with and without spaces), lines, words, sentences and
paragraphs in a text document. Unfortunately, I've run into trouble: the
numbers don't seem to be coming out right.

Attached is the text file, for testing purposes, and below is the
source:

lines = File.readlines("text.txt")
line_count = lines.size
text = lines.join

puts "#{line_count} lines."

total_characters = text.length
puts "#{total_characters} characters."

total_characters_nonspaces = text.gsub(/\s+/, '').length
puts "#{total_characters_nonspaces} characters, excluding spaces."

word_count = text.split.length
puts "#{word_count} words."

paragraph_count = text.split(/\n\n/).length
puts "#{paragraph_count} paragraphs."

sentence_count = text.split(/\.|\? |!/).length
puts "#{sentence_count} sentences."

Here are the results I get:
42 lines.
6446 characters.
5315 characters, excluding spaces.
1130 words.
2 paragraphs.
44 sentences.

Any and all help/advice would be appreciated.
