Alternatively, you can take a look at the 'teaching accidental style, which 
explicitly displays the accidentals implied by the key signature as warning 
accidentals.
The cooll thing about this style is that if two equal pitches succeed each 
other, the second one never gets an accidental, but if there is at least one 
note in between, the second one does. E.g. if you have 

\relative c' {
  \key es \major
  #(set-accidental-style 'teaching)
  es es g e 
  es g es e |
}

Then the in the first measure the second es will not get an accidental (since 
it immediately follows another es), while in the second measure the second es 
will get an accidental (since it follows a different pitch)...

The definition of the teaching style is in scm/music-functions.scm...
Attached is a starting point where you "only" need to take the my-madrigal-
accidental-rule and adjust it to your own use case (yeah, I know, that sounds 
so easy... To be honest, I haven't digested the code to exactly understand how 
to adjust the rul.)...

Cheers,
Reinhold
