Positioning of "8" under clef symbol in G_8 clef

[Nick Payne]

The default positioning of the small "8" under the clef symbol when 
using the treble_8 or G_8 clef is too far to the right. It looks better 
when the X-offset is about 0.7 staff units:

%============
\version "2.17.10"

\relative c'{
  \clef "G_8"
  \override Staff.OctavateEight.X-offset = #0.7
  c d e f
}
%============
