That looks like my ugly hack. I came up with it shortly after the 
disclosure of the "ShellShock" vulnerability.

The reason to do this when replacing a login shell or (most importantly) 
the system shell at /bin/sh is that you do not want either of those to 
be breakable by modification of a shared library installed by MacPorts.

The primary reason that one should replace /bin/{bash,sh} with a newer 
version on older versions of MacOS X is ShellShock.
