make-engraver helper macro

make-engraver helper macro

Two commits, the actual new functionality being introduced in
scm/translation-functions.scm (is that the proper place?), and the
rest just usages of this macro.

This is an evidently upwards-compatible change.

Looks excellent to me!

Makes Scheme engravers much more accessible.

Thanks,

Carl

Well, it is just syntactic sugar (or rather skimming).  But it would appear that
working with quoting and quasiquoting and unquoting and cons and lambda and list
even on an elementary level is rather scary to people not quite into Scheme, and
you don't have to enter "any of this nonsense" manually.  It turns out that the
commit putting this macro to use removes about as much lines as the commit
defining the macro adds.

I am not particularly happy about the discoverability.
