Is it possible that there was a line break in the middle of the URL when you pasted it into your reply? Line breaks are changed to break tags when a reply is submitted.
If that's not it, the only other thing I can imagine is that the post text got wrapped, and the URL was long enough that it was cut up in the wrapping. Here's my test:
http://cisco.com/en/US/products/hw/s...08007eac0.html
Edit It's being wrapped by the thread display code... looking into that now.
