Accidentals misalignment depending upon ledger line numbers

[Pierre Perol-Schneider]

Hi Bug Squad,
Please consider those inconsistent alignment:
\version "2.19.83"
{ %% just a vertical line:
  s1\mark\markup\with-dimensions-from\null\with-color #red
\draw-dashed-line #'(0 . -200)
  a!4 }
{ s1 f!4 }
{ s1 c'''!4 }
{ s1 e'''!4 }
{ s1 ais4 }
{ s1 fis4 }
{ s1 cis'''4 }
{ s1 eis'''4 }
{ s1 aes4 }
{ s1 fes4 }
{ s1 aes''4 }
{ s1 ces'''4 }
%%

Possible workaround:
{ %% just a vertical line:
  s1\tweak extra-offset #'(.8 .
0)\mark\markup\with-dimensions-from\null\with-color #red \draw-dashed-line
#'(0 . -30)
  a!4 }
{ s1
  %% workaround:
  \once\override Staff.BarLine.extra-spacing-width = #'(0 . 1.3)
  f!4 }

Cheers,
Pierre
