monkey-patching sgmllib breaks other libraries

[GoogleCodeExporter]

What steps will reproduce the problem?
1. import feedparser, use any other library relying on sgmllib
2. do not import import feedparser, use any other library relying on sgmllib
3. the results may be different

feedparser replaces sgmllib.endbracket for every other library.

This causes this bug (with Mechanize): https://symlink.me/issues/649 which is 
present only when feedparser is imported.

I think I've fixed this in a github branch at:

https://github.com/kurtmckee/feedparser/tree/issue271

I'd really appreciate it if you would test the code (direct link below) and 
report back if it fixes the Mechanize issue you mentioned above.
