Remove space before end-of-sentence dot in debug output

It may get quite annoying when showing up each time an application
starts up on developer machine, which in my case was too often enough
to get irritated to the point where I just spend time actually fixing
it.

Grammar was messed up in ae8c8fdf

, it used to spell:

> "... for the" << locale << "language. Search paths" ...

So, it made sense before removal of the "language" word.
