Embedded decimal causes title to be truncated

Hi,  I've got journal entries with a title like: `Ran 5.2 miles. <Run report>` and when it gets added to the journal, the entry ends up looking like:
     `2013-03-28 21:43 Ran 5.
      2 miles. <Run report>`

I made a one line change that looks for a `.!?` _and_ a space afterwards before considering it to be a title.

Please consider if the modification looks ok.
Thanks.
