Summary: file.read() truncating strings under Windows

Initial Comment:
On Python 2.4.4 and 2.5.1 under Windows, file.read() fails to read a varying number of characters from the last line(s) of text files when asked to read more than 800 characters from near the end of the file. For example, if the last word of a 500kb file is "superlative", file.read() might output "erlative". The file pointer at this stage is very close (a few words at most) to the end of the file. I ran into this problem while writing a program to split .txt ebooks into smaller files so that my ancient iPod could handle them. The behaviour is identical on both 2.4.4 and 2.5.1 under Windows, but does not appear under Mac OS X. I was unable to test it under Linux. To test the bug, I used various books from http://gutenberg.org . The one primarily used was Pride and Prejudice by Jane Austen.
