Bug in 2.13.x?

[Tim McNamara]

I had posted previously about having .ly file fail to compile in 2.13.44-1 
which worked in 2.12.  This was not repeatable for others.  I tried downloading 
2.13.45-1 and it, too, fails.  The error massage is:

/Applications/LilyPond.app/Contents/Resources/share/lilypond/current/scm/chord-ignatzek-names.scm:208:9:
 In procedure chord-name->pop-markup in expression (name-root root 
lowercase-root?):

/Applications/LilyPond.app/Contents/Resources/share/lilypond/current/scm/chord-ignatzek-names.scm:208:9:
 Wrong number of arguments to #<procedure chord-name->pop-markup (pitch)>

I had a look at the lines specified, comparing 2.13.45-1 with 2.12.3-1.

Here's the lines from 2.13.45-1 (200-214):

 (define (ignatzek-format-exception
           root
           exception-markup
           bass-pitch
           lowercase-root?)

    (make-line-markup
     `(
       ,(name-root root lowercase-root?)
       ,exception-markup
       .
       ,(if (ly:pitch? bass-pitch)
            (list (ly:context-property context 'chordNameSeparator)
                  (name-note bass-pitch #f))
            '()))))


And the comparable lines from 2.12.3-1 (188-201):

(define (ignatzek-format-exception
           root
           exception-markup
           bass-pitch)

    (make-line-markup
     `(
       ,(name-root root)
       ,exception-markup
       . 
       ,(if (ly:pitch? bass-pitch)
            (list (ly:context-property context 'chordNameSeparator)
                  (name-note bass-pitch))
            '()))))


I don't speak Scheme and have no idea if the differences are important or are 
the cause of the problem I am seeing.  But there is a difference:  note that in 
2.13.45-1, we find:

     ,(name-root root lowercase-root?)

whereas in 2.12.3-1 we find:

     ,(name-root root)

Is that what the error message is complaining about (too many arguments)?  And, 
if so, why would this fail on my computer and not on the computers of other 
people?  Compiling fails on on 2.13.44 and 2.13.45-1 with every one of my files 
that use \chordmode.  It doesn't matter which editor I use (Emacs, Aquamacs, 
Fraise/Smultron or the built-in editor in the Mac package).
