Bug: Rufo breaks HEREDOC syntax

[ivoanjo]

While looking into #83 I tried rufo on a number of repositories for commonly-used gems and came across a few issues.

This one is a testcase extracted from the pry gem.

Example code:

puts (<<-HELLO
  hello world
HELLO
)

which after running rufo turns into

puts (<<-HELLO
  hello world
HELLO)

which is now invalid:

$ ruby heredoc.rb 
heredoc.rb:3: can't find string "HELLO" anywhere before EOF
heredoc.rb:1: syntax error, unexpected end-of-input, expecting tSTRING_CONTENT or tSTRING_DBEG or tSTRING_DVAR or tSTRING_END
puts (<<-HELLO
              ^
