Underscores in links can generate undeeded em tags

As an example:

[ http://www.mysite.com/my_folder/file/](http://www.mysite.com/my_folder/fil e/) to read the report. Also see: at
http://www.mysite.com/test?q=xx_yy to test.

Generates

http://www.mysite.com/myfolder/file/ to read the report. Also see: at http://www.mysite.com/test?q=xxyy to test.

This site shows the output from various processors, showing others also
exhibit this problem. http://babelmark.bobtfish.net/?markdown=%5Bhttp%3A%2F%2Fwww.mysite.com%2Fmy _folder%2Ffile%2F%5D%28http%3A%2F%2Fwww.mysite.com%2Fmy_folder%2Ffile%2F+%2
