Comment #8 on issue 2178 by [email protected]: NR: clarify the subsection "Automatic accidentals" of section 1.1.3
http://code.google.com/p/lilypond/issues/detail?id=2178
It does make sense to fix the behaviour before attempting to fix the documentation, at least here, where the fix looks straightforward. (ah, hope that doesn't come back to haunt me :) I'll open a new issue to clear old accidental rules first, and set it to block this issue.
