6.1 and further changes to the language

[Jason Garber]

Thanks so much!  I just used it in SuperRedCloth.  Example:
link = ( "["? '"' C "."* " "* link_says " "* :> title? :> '":' %A uri %
{ STORE_URL(href); } :> "]"? ) >X ;
The optional square bracket at the end wouldn't have been possible (or
at least as simple) before.

Looking forward to the 6.1 release.
