1) Is there a reason to use explicit 'register' variables nowadays?
This encumbers sources with no measurable benefits; moreover,
some GC tracing/debugging techniques assumes that you can take
an address of any Lisp_Object, which is effectively blocked by
using 'register'.
2) Why still using ^L? It looks like a huge empty space in patches
showing as attachment in some e-mail clients, and I'm curious
whether someone still uses a printing system relying on ^L page
breaks :-).
