This patch is taken from r1441 of rubygems's SVN repository to fix
rewriting of /usr/bin/env shebang patch with additional arguments to
the ruby interpreter. Without the patch the regexp would not match,
leaving the /usr/bin/env in place. This causes problems on platforms
that pass the remainder of the shebang line as a single argument, such
as Linux. See bug #199378 for all the details.

This patch should no longer be needed with rubygems 0.9.5.
