commit 64b35b506420a7e9a00af47fe8d0c283759aa4f6
Author: Ralf Wildenhues <address@hidden>
Date:   Sun Mar 22 09:39:14 2009 +0100

    Minor optimization in parallel-tests text box creation.
    
    * lib/am/check.am [PARALLEL-TESTS] (am__text_box): Use only one
    awk invocation, rather than several tools, to create a text box.
    Suggestion from Akim Demaille.
