* We need a `final_new_line` to make our source code as text file, per
  POSIX and C specification.
* `bloom_filters` should be limited to interal linkage only

Hi Junio,

This patch by Danh seems to have slipped through the cracks, so I decided to pass it along. The original version of this patch (which I don't seem to be able to find) clashed with one of Jeff's series [1], because they both fixed up a 'No newline at end of file' issue with test-bloom.c. Also as Danh points out [2], the original patch didn't fix up the test files.

Anyway, this fixes up some 8 sparse warnings on 'master' and 'next':

  $ diff sp-out sp-out1

  < bloom.h:90:6: warning: no newline at end of file
  20,22d18
  < bloom.c:276:1: warning: no newline at end of file
  < bloom.h:90:6: warning: no newline at end of file
  < bloom.c:12:26: warning: symbol 'bloom_filters' was not declared. Should it be static?

  < ./bloom.h:90:6: warning: no newline at end of file
  < t/helper/test-bloom.c:6:30: warning: symbol 'settings' was not declared. Should it be static?
  $ 
  
... along with a further warning on 'pu', due to the 'ds/line-log-on-bloom'
branch adding another '#include "bloom.h"'.
