Bug #11914: 2.2.4: Parsing "symbol:%w(word)" gives SyntaxError

* ruby -v: ruby 2.2.4p230 (2015-12-16 revision 53155) [x86_64-darwin14]
* Backport: 2.0.0: DONTNEED, 2.1: DONTNEED, 2.2: DONE, 2.3: DONTNEED
----------------------------------------
This snippet does not parse correctly, only in ruby 2.2.4: {a:%w(a)}
Adding a space after the "a:" works.

    irb(main):001:0> RUBY_VERSION
    => "2.2.4"
    irb(main):002:0> {a:%w(a)}
    SyntaxError: (irb):2: syntax error, unexpected '%'
    {a:%w(a)}
        ^
    (irb):2: syntax error, unexpected '}', expecting end-of-input
    	from /Users/allen/.rbenv/versions/2.2.4/bin/irb:11:in `<main>'
    irb(main):003:0> {a: %w(a)}
    => {:a=>["a"]}

This works (without the space) in 2.2.3 and 2.3.0

Work-around: add the space after the colon.

My search failed to find an existing issue, but hope this isn't a repeat.

Thanks!
