Measure-initial spaces confuse propotional spacing

[Trevor Bača]

Hi,

Proportional spacing together with uniform-stretching should cause all
three of the one-measure scores below to express exactly the same
line-length.

The first two scores do express exactly the same line-length. But the
third score fails.

The reason appears to be because the third score begins with a
measure-initial skip.

%%% BEGIN %%%

\version "2.11.0"

\layout {
  ragged-right = ##t
}

\new Score \with {
  \override SpacingSpanner #'uniform-stretching = ##t
  \override SpacingSpanner #'strict-note-spacing = ##t
  proportionalNotationDuration = #(ly:make-moment 1 16)
} {
  \new Staff \with {
     \remove Separating_line_group_engraver
  } {
     \time 4/4 c'4 c'4 c'4 c'4 % WORKS GREAT
  }
}

\new Score \with {
  \override SpacingSpanner #'uniform-stretching = ##t
  \override SpacingSpanner #'strict-note-spacing = ##t
  proportionalNotationDuration = #(ly:make-moment 1 16)
} {
  \new Staff \with {
     \remove Separating_line_group_engraver
  } {
     \time 4/4 c'4 s4 s4 s4 % WORKS GREAT - SKIP NOT AT BEGINNING
  }
}

\new Score \with {
  \override SpacingSpanner #'uniform-stretching = ##t
  \override SpacingSpanner #'strict-note-spacing = ##t
  proportionalNotationDuration = #(ly:make-moment 1 16)
} {
  \new Staff \with {
     \remove Separating_line_group_engraver
  } {
     \time 4/4 s4 s4 s4 s4 % BUG - SKIP AT BEGINNING OF MEASURE
  }
}

%%% END %%%
