That won't work, at least not as long as LilyPond decides to deviate
from the GNU standards.  You'll need to make a special exception
for LilyPond, something like this

    (defun lilypond-c-mode-common-hook ()
      (setq indent-tabs-mode nil))

    (defvar lilypond-c-mode-directory-regexp
      ".*/vc/\\(lilypond-*\\).*"
      "Regexp that matches directories into your LilyPond source tree.")
    (setq lilypond-c-mode-directory-regexp ".*/vc/\\(lilypond-*")

    (defun conditional-ooo-c-mode-common-hook ()
      (when (string-match lilypond-c-mode-directory-regexp buffer-file-name)
        (message "Using LilyPond code settings")
        (lilypond-c-mode-common-hook)))

...but then also for scm and texinfo files.

Maybe we can start a repository at savannah that collects snippets
like this for all types of editor and all projects that decide to
add a little enhancement over the standard coding settings?  What
do you think?  That would make it fairly easy to cater for all kinds
of different standards!
