It's "valid", but I think any software that's supposed to guess what
the actual URL is should guess that it's "http://www.bleah.com", and
that the period is not part of the URL.

If I add support for this to Markdown, and you really do want to
include a period (or comma or semi-colon) in the actual URL, then
you will have to use angle brackets to delimit it:

  <http://example.com/.>
