Failure to parse tab-indented heredoc

[agaffney]

Parsing fails when a tab-indented heredoc is encountered.

Example (the below should have tabs, but I cannot enter one directly and can't find a convenient place to copy/paste one from):

        someparam = <<-EOF
        some content
        some more content
        EOF

The error that I got:

I think #32 should resolve this. There wasn't any support for <<- style heredocs.

Verified fixed in 0.3.8...thanks!
