the lua strfind/gsub is somewhat limited. there is no way you can do this in
one pass.
(you could use a gsub pass to translate all "+=" into some single character
first)

the posix regexp lib is rather large. (larger than the rest of lua)
but there is a library to plugin to lua mentioned on the addon page:
http://www.lua.org/addons.html
http://www.dcs.gla.ac.uk/~rrt/lua.html (it seems to be down at the moment?)
ah, it seems to have moved to http://www.mupsych.org/rrt/ (someone update
the addons page ;)

Nope. At least not with the simple default Lua executable.
Again, have a look at the http://www.lua.org/addons.html page.
You can find lots of Lua-Based Shells / Editors listed there.
