#+PROPERTY: for babel header args worked... then it didn't

[James Harkins <jamshark70@gmail.com>]

Wee bit of frustration with Babel just now.

Some weeks ago, I wrote a Beamer presentation with LilyPond source code 
blocks. I needed to add a little code to each example to suppress the 
"tagline" from each results file. In that presentation, setting the 
:prologue header argument in a #+PROPERTY line worked perfectly:

#+PROPERTY: header-args:lilypond :prologue \header{tagline=##f}

Now I'm working on a short article-class document, and I included the same 
#+PROPERTY at the top, and... no effect. But... *the lines are identical*. 
??

":prologue \header{tagline=##f}" does take effect if I include it in every 
#+begin_src line. That's an acceptable workaround for this file, since 
there won't be many examples.

But it bothers me when I figure something out, and then I try to do it 
again, and it doesn't work. It's like 1 + 1 = 2 in one place, and 1 + 1 = 0 
in another.

Why would "#+PROPERTY" work in one file and be ignored in the other?
