Why non-escaped newlines are prohibited in single-quoted string literals?

[Egor Skriptunoff <egor.skriptunoff@...>]

Hi!

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

B'

local str2 = 'A\

B'

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.
