Granted, it should be changed so that the first star or underscore is also not preceded by an odd number of backslashes and the second symbol is not preceded by an even number of backslashes, I did forget to take those into account. But the command was not working properly in the first place. So neither the original version nor my version are correct, as far as I understand. Please correct me if I am wrong.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV><BLOCKQUOTE type="cite"><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">What was the problem you were trying to fix?</DIV></BLOCKQUOTE><DIV><FONT class="Apple-style-span" color="#0000DD"><BR class="khtml-block-placeholder"></FONT></DIV>The problem was posted by Xavier Noria: <A href="http://thread.gmane.org/gmane.editors.textmate.general/4601">http://thread.gmane.org/gmane.editors.textmate.general/4601</A></DIV><DIV>This is his message:</DIV><DIV><BLOCKQUOTE type="cite"><BLOCKQUOTE type="cite"><DIV>Hello!
