 rubygems can no longer parse gem specs if they contain strings that were
 assigned from a here doc.

 Example:
 {{{
   s.description   = <<-EOS
 HotCocoa is a Cocoa mapping library for MacRuby.  It simplifies the use of
 complex Cocoa classes using DSL techniques.
   EOS
 }}}

 That example worked fine about a week ago. The gem will build without
 error, but it will not install and I will get the following error:

 {{{
 scanning error encountered during parsing: could not find expected ':'
 (line 65, column 0), context while scanning a simple key (line 64, column
 0)
 }}}

 If I unpack the gem and look at the decompressed metadata.gz, I find these
 at lines 64-66:

 {{{
 description: |
 HotCocoa is a Cocoa mapping library for MacRuby.  It simplifies the use of
 complex Cocoa classes using DSL techniques.
 email:
 }}}

 If I change the gem spec to not use a here doc then the gem builds and
 installs properly.

 {{{
   s.description   = <<'
 HotCocoa is a Cocoa mapping library for MacRuby.  It simplifies the use of
 complex Cocoa classes using DSL techniques.
   '
 }}}

 And in the unpacked metadata.gz I see the following:

 {{{
 description: "\nHotCocoa is a Cocoa mapping library for MacRuby.  It
 simplifies the
   use of complex Cocoa classes using DSL techniques.\n  "
 email:
 }}}

 This broke pretty much all of my projects since I always use here docs for
 the description of the gem.
