Cut-and-paste merge repair 

On 27 June 2006, Pjacobi replaced this article with a redirect to Yull Brown and merged the contents into the latter.  This was a perfectly well done merge, execpt for the fact that the target article was a very short stub, and the result was thus an unbalanced article that mostly discussed something other than its stated topic.  In effect, it was almost, but not quite, a cut-and-paste move.  Since, a month after the merge, there has been no sign of improvements in this regard, I've moved the merged page back to Brown's gas so that the name of the article matches its main subject.  I've also fixed the page histories so that the edits made to Yull Brown after the merge are now at Brown's gas, where they properly belong.  —
