We do need to escape the user's input appropriately here - indeed I
think it may already be escaped but not correctly if so (the composer
etc input is done in scheme). But there is a more powerful thing we
could be doing now we have our own LilyPond parser in scheme: we could
check the syntax of any user-generated lilypond text. It would be a
matter of providing top level rules or just running the lexer to check
for a given token (e.g. in that case the STRING token)
