I don't want to add any arbitraryfiletypes. We should limit the list of filetypes to those which are commonly used. I think this "abc" should not be added.
well, it's a pity because every major text editor I know has support for abc:
- Emacs has an external plugin:
http://www.geocities.com/mkjunker/abc-mode.el.html
(It's also easier to include external support for this kind of editor because they don't need to be recompiled)
- Vim has built-in syntax hightlight for ABC, it's included in the svn:
http://vim.svn.sourceforge.net/viewvc/vim/vim7/runtime/syntax/abc.vim?revisi...
- Kate has built-in syntax highlight too: http://websvn.kde.org/trunk/KDE/kdelibs/kate/syntax/data/abc.xml?view=markup
I'm developping also a linux live-cd dedicated to the use of ABC notation, among other things. It uses the Gnome desktop and Geany as the main text editor:

I can patch myself every new release of Geany to get the abc support, but modifying 6 files just for this is quite an heavy work.
Only Geany has such amazing feature such as the tagmanager, it's the reason I wish Geany can support many filetypes. If it was only a matter of including a definition file into my ~/.geany, I wouldn't bug you for including it into the svn, I'd only propose it on my website.
Here is a picture of Geany displaying a tunebook: http://anamnese.online.fr/site2/esclinux/kde_geany_abc1.png
