I didn't mean GNU/XEmacs as-is, but rather an editor built on the same
principles of extensibility/customizability/self-documenting/etc. but
with Lua instead of elisp. Sorry; the word "Emacs" is pretty
ambiguous. Let's just take it to mean "editor macros". :)

Indeed, it's a portability nightmare... XEmacs is immeasurably better
in terms of code cleanliness, porability, and lack of 1980's-style
implementation hacks, but sadly it's unusably outdated and corrupts
UTF-8 files (even many fully valid ones) when you load and resave them
due to conversion to/from legacy MULE charset which is not a superset
of Unicode. So I'm still using GNU Emacs..
