  The \pstree at horizlevelsepadjust must have no argument. His definition was
falsely copied from \pstree at vertlevelsepadjust, which require one.

  From CHANGES file:

  * 97/09/24 pst-tree.tex (0.93-97 patch 2): The \pstree at horizlevelsepadjust
doesn't require an argument - definition was falsely copied from
\pstree at vertlevelsepadjust, which require one
(reported by Denis Girou <Denis.Girou at idris.fr>)

  My test case is (result will be the same, just the erroneous output message
will be suppressed):

\documentclass{article}

\usepackage{pst-tree}

\pagestyle{empty}

\begin{document}

\pstree[treemode=R,levelsep=*1cm]{\TC*}{\TC* \TC*}
