Well, despite strong development of Denemo over the last few years your

That worked fine, which gave me confidence that the lilypond.lang file
hadn't been corrupted in transmission. The reason I wanted to use a
local-to-denemo lilypond.lang file for Denemo is that I wouldn't want
the Denemo installation to override the user's own file (if such
existed), and I could easily imagine problems getting the syntax
highlighting working on non-gnome systems. 
The GtkSourceView allows you to set a search path for the .lang files
but it turns out that your .lang file relies in turn on some
default .lang file and so I needed to keep the standard search path and
just prepend the path to my copy of lilypond.lang inside Denemo. That
done it is now working nicely. Thank you very much!
