Feature #4513: allow whitespace following EOL continuation backslash
https://bugs.ruby-lang.org/issues/4513#change-71208

* Author: Rich_Morin (Rich Morin)

* Priority: Normal

----------------------------------------
In a few programming languages, the displayed or printed program can hide
critical syntactic and/or semantic information.  For example, in make(1)
and Python, the difference between initial tabs and spaces can cause bugs
that are not visually apparent.

Ruby has a minor instance of this problem, in that spaces or tabs
between a backslash and the EOL will prevent the line from being continued:

 >> a \
 ?> = 2
 => 2
 >> b \ 
 SyntaxError: compile error
 (irb):3: syntax error, unexpected $undefined, expecting $end
 	from (irb):3

Could Ruby open up its syntax to allow any number of intervening spaces or tabs before the EOL?
