Use directory-local variables to establish some coding styles in Emacs (issue 6460109)

[ianhulin44]

Do we need to add anything to the standard .gitignore for these?

They're files in the git directories for developers developing the kit
rather than users writing code.

Quite a lot of developers have the build directory within the git tree.

There are already .el files in the kit for lilypond mode in emacs.

Is this an issue for *this* patch?

Just some issues possibly coming in from the blind side.

Cheers,
Ian
