Hello all,

Please find attached a (hopefully minimal enough) example of problems with  
the 'strict-grace-spacing = ##t setting described in:
http://lilypond.org/doc/v2.15/Documentation/notation/special-rhythmic-concerns#grace-notes

... in the snippet "Positioning grace notes with floating space". As you  
can see, there are a bunch of notational clashes:

  * the first set of grace notes overlap the time signature (they would also
    overlap the key signature if one was present);

  * the accidental on one of the grace note clashes with the preceding grace
    stem and notehead;

  * in the 2nd bar, the first grace notehead clashes with the  
preceding "real"
    notehead.

These kinds of clashes are referred to in a 2008 email on the lilypond-user
list:
https://lists.gnu.org/archive/html/lilypond-user/2008-09/msg00586.html

... but I don't see a corresponding bug report.

Minimal example (by Marek):
\version "2.15.40"
{
  \override Score.SpacingSpanner #'strict-grace-spacing = ##t
  \relative c'' { \grace { c16[ d e fis] } g2.}
}
Original file gives more examples.
