Teach for-each-ref about a little language called Tcl.
Love it or hate it, some people actually still program in Tcl. Some of those programs are meant for interfacing with Git. Programs such as gitk and git-gui. It may be useful to have Tcl-safe output available from for-each-ref, just like shell, Perl and Python already enjoy. Thanks to Sergey Vlasov for pointing out the horrible flaws in the first and second version of this patch, and steering me in the right direction for Tcl value quoting. Signed-off-by: Shawn O.
