Filetype detection differences on Windows

Some of the tests have different results on Windows:

```

In the case of `test_filetest_code_java_logger_56`, different filetype, mimetypes, and file size were detected:

Expected result for `test_filetest_code_java_logger_56`:
```
filetype_file: Java source, ASCII text
mimetype_file: text/x-java
mimetype_python: text/x-java-source
filetype_pygment: Java
programming_language: Java
is_file: yes
is_regular: yes
size: 6800
is_text: yes
contains_text: yes
is_source: yes
```

Result for `test_filetest_code_java_logger_56`:
```
filetype_file: ASCII text, with CRLF line terminators
mimetype_file: text/plain
mimetype_python: text/x-java-source
filetype_pygment: Java
programming_language: Java
is_file: yes
is_regular: yes
size: !!int '7013'
is_text: yes
contains_text: yes
is_java_source: yes
is_source: yes
```

The detected types and size should be the same. The other failing tests have similar issues.
