Here's the narrow_tree patch for mutt 1.3.25. Daniel Eisenbud
originally wrote this patch for old versions of Mutt (before 1.0).
Then, this patch wasn't supported any longer. But as I still need
it, I modify it each time it need be, but with the risk of breaking
things...
I've tested it only with my configuration, and I don't know about
specific configurations. Use it at your own risks...
