Back-port the \ulink macro to the documentation package for Python 2.1.x

freddrake · freddrake · commit 4fa82fa410bd · 2002-08-27T19:50:42.000Z
since a documentation patch included \ulink.  Adding this here makes
back-porting further documentation patches easier than having to remove
\ulink from the patches.
Closes SF bug #598996.
