tango.text.Util is a mess

[SiegeLord]

Try to figure out how to make it work nicely. Note that inout everywhere does NOT work, since I haven't been able to get fructs to work with them.

error on tango/text/Util.d with dmd 2.059

tango/text/Util.d(1383): Error: delegate dg (ref const(char)[] token) is not callable using argument types (char[]) tango/text/Util.d(1391): Error: delegate dg (ref const(char)[] token) is not callable using argument types (char[])

I couldn't reproduce that specific error, but it did change that function a bit so maybe it went away?

Yes, this error went away. good work!
