Wow, you are really pushing the limits here.  Good!

Unfortunately, the patch broke several existing unit tests.  But I think 
I got it working the way you want (more or less) without breaking anything.

First some commentary:

The current way of adding literal file name to a list of rule dependents 
is to wrap it in a lambda, e.g.

    rule '.o' => ['.c', proc{"Rakefile"}] do |t| ... end

I added code to handle non-extension file names directly, so now the 
following will work:

    rule '.o' => %w[.c Rakefile] do |t| ... end

Unfortunately, names beginning with dots are assumed to be file 
extension patterns.  If you really need it, wrap it in a lambda as 
above, or use something that is obviously not an extension, e.g:

     rule '.o' => %w[.c ./.foo] do |t| ... end

Code to handle the above has been committed.

If you are not matching a pattern in the rule, why don't you just use a 
normal task?  Nevertheless, this should work with the recently committed 
code.

Does this work for you?
