Possbile Pry indentation bug inside indented input with heredocs

repro_case

Pry's handling of heredocs within existing indented
blocks such as method definitions. Steps to reproduce:

1. start pry
2. start a method definition
3. Open <<EOF style heredoc (as opposed to <<-EOF)
4. Type any text
5. Close the heredoc
6. End the method
7. Observe that the input buffer does not close until it is cleared with '!'

Probable cause: The outre indentation level is not stripped from the space-sensitive HEREDOC thus it can never close.
