How should these be handled?

  "foo\n\n\n"
  "foo\n\r\n\r"

etc.

In other words, does the chomp() method always remove 0-2 characters, or all
trailing /n/r characters? Is it a good idea to add a string method that
makes assumptions about what the file.readline and file.readlines methods
return? Wouldn't it be cleaner to enhance the file object with additional
methods:

  f. readline_chomp()
  f.readlines_chomp()

Or perhaps add an attribute to the file object to indicate if newlines
should be stripped for text files?

  f.chomp = 1  # 1=strip trailing /n and /r characters, 0=leave them
(default)
