Title: fixes #3838, $(document).height() incorrect in IE6

```
jQuery Size - compared to last make
251336 (+309) jquery.js
94476 (+21) jquery.min.js
33513 (+9) jquery.min.js.gz
```

a few notes, Thoughts please!:

1. there is a slightly smaller way to do this involving `Math.min` first which saves 4 bytes, but clarity really suffers and the casual link as to why it works gets lost. I'd prefer to eat the 4 bytes.

2. I used a new convention: `// support:IE6` which helps facilitate the work I'm doing for http://jqbug.com/11164 . It's going to be used to highlight the true cost of supporting each browser, by explicitly calling out browser compat issues throughout the code rather than just in support.js
