As far as I can tell, neither Lua nor Scite has Problems with (very) 
long lines.
Try the following script script to check your editors and luas capabilities:

local lua=io.open("longstrings.lua","w")
local len=1
while len<=8*1024*1024 do
    lua:write("str=\"",string.rep("X",len),"\"\nprint(#str)\n")
    len=len*2
end
lua:close()

The created line opens with scite and runs with lua.

>lua -e "io.stdout:setvbuf 'no'" "longstrings.lua"

(I stopped a 8MB string, but I believe, you even could try more)

And as I dont believe, you will enter this lot of binary data by hand, 
but will use some loaded or generated data as source, why dont you put 
these into a own files?
Example:

Generating the file

local lua=io.open("bindata.lua","w")
lua:write("return \"")
-- whatever you do to generate the binary data, this is just an example
for i=1,1000 do
    lua:write(string.format("\\%03d",(math.sin(i/1000)+1)*127))
end
lua:write("\"\n")
lua:close()

The file then looks like (trunkcated here in the mail(

return "\127\127\127\127\127\127 ....\233\233\233\233\233\233\233\233\233"

then you can use it with

local bindata=require"bindata"
print(#bindata)
for i=1,#bindata do
    print(i,string.byte(bindata,i))
end

There will be no need to modify bindata.lua in the editor.

Hope, this gives you an idea
