Sure, sounds reasonable as a default, at least.  But perhaps there
should be a way to allow JIT in --batch?  It looks like currently the
only way is to set `noninteractive', which has wider side effects.

Yet Another Variable here would be possible, but perhaps some other
mechanism would be nicer.  Hm...  Perhaps
inhibit-automatic-native-compilation should be refashioned into
something else, like `native-compilation-types' or something, and would
default to 'all in non-batch, but could be 'force to force it even in
--batch?  (And possibly also 'trampoline to save trampolines without
doing any more JIT-it, like Stefan M sort of suggested.)
