Ok.  NR 1.1.1.  I would consider that to be "under" NR 1.1, but I
admit that I forgot the final .1.

Well, first start off with a simple example:

\version "2.11.65"
\relative c'' {
   c4(
   \once \set suggestAccidentals = ##t
   cis d4.) c8
}

Hmm, it prints an error message.  It would be helpful to report
this to the bug list.


Then try to make it behave properly:

\version "2.11.65"
\relative c'' {
   \override AccidentalSuggestion #'avoid-slur = #'inside
   c4(
   \once \set suggestAccidentals = ##t
   cis d4.) c8
}

Nope, it ain't moving.  Let's make sure that there's enough space:

\version "2.11.65"
\relative c'' {
   \override Slur #'ratio = #8.0
   \override Slur #'height-limit = #8.0
   \override AccidentalSuggestion #'avoid-slur = #'inside
   c4(
   \once \set suggestAccidentals = ##t
   cis d4.) c8
}

Still ain't working.  OK, time for another bug report.  Oh wait;
first do a quick search to see if this has been reported before:
http://code.google.com/p/lilypond/issues/list?can=1&q=suggestAccidentals
(I forgot this step just a day or two ago, and boy did I feel like
an idiot!)

Nope, not reported.  So now you send those two bug reports to the
bug list, and use some ugly hack with #'extra-offset and the Slur
overrides to get the output you want.  It's not pretty, but even
lilypond has bugs.  In fact, over 200 of them!

Once you've identified bugs, report them, use a workaround (and in
my experience, extra-offset is almost always the cheapest, easiest
thing to do) and get on with life.
