I spent some time experimenting with html-formatted help commands.  I 
quickly came to the conclusion that this was a bad idea: using <pre> will 
not look good enough, and it is out of the question to hand-format docs 
twice.

Instead, Leo will load docutils from leo/extensions if an initial import of 
docutils fails.  That way, newbies will see the best-possible help 
commands, without having to explicitly install docutils. I'll soon be 
upping new code with fallback imports using g.importExtension.

There seems to be a problem with docutils on Windows with Python 3.x.  The 
docutils docs say that 2to3 is run "on demand", but that doesn't appear to 
be working.  Happily, it took just a few seconds to run 2to3 on the 
docutils-0.10/build folder, and a few more seconds to copy that to my 
Python 3.3 folder.  This is, iirc, the *first* time I have ever 
successfully run docutils with Python 3.x.

In short, distributing a fallback copy of docutils with Leo makes sense to 
me.  It eliminates dual documentation, and should ensure that all Leo 
newbies will see good-looking docs.  The downside is that the docutils 
folder is about 2.7 meg.

Your comments, please.
