I'm not sure exactly how the internals of capitalize work, but based on 
its output it does not blindly subtract 35 from the ascii code for the 
first character of a word.  So, internally capitalize sorts out which 
characters to capitalize and which characters to leave alone(e.g. 
capital letters, punctuation, spaces).

It is possible to use ruby to skip  the useless call to capitalize for 
words that are spaces, like this:

    if word == " "
      print word
    else
      print word.capitalize
    end

but it turns out that(on my system at least) using that if statement is 
fractionally slower than letting the C code in the capitalize method 
take care of words that are spaces.
