I have a suggestion to allow using of non-escaped newlines
in literal strings delimited by single or double quotes.
I think it would be handy all these three definitions to be
syntactically valid and equivalent:
local str1 = 'A
local str2 = 'A\
local str3 = 'A\nB'
Currently, the definition of str1 gives syntax error.
I don't see any problems that could appear by enabling syntax
used for str1.
I think Lua would be a bit more comfortable to use
with unnecessary prohibition removed.
