Attempting to slurp a string on the last line barfs instead

[cwfoo]

To reproduce:

1. Open a Scheme file (myprogram.scm), and insert the following on the last line:

   (define s) "hello"

2. Position the cursor on the closing parenthesis, and try to slurp the string (<Leader>>).
3. Observation: paredit barfs the identifier instead.

   (define) s "hello"

This behavior only seems to occur when the string is the very last item on the last line of the buffer.

[cwfoo]

Wrong repository. Sorry about that. Here's the issue in the paredit repository: https://github.com/kovisoft/paredit/issues/40
