[sr-dev] append_branch() change

[Miklos Tirpak]

hi,

I was recently fighting with a serial forking issue, and figured out 
that t_relay() automatically appends a new branch when the RURI has been 
changed. This means to me that the config below becomes incorrect:

failure_route["abcd"] {
		...
                 rewritehostport("127.0.0.1:5062");
                 append_branch();
                 t_relay();
}

I saw two branches created with the same RURI and sent to the same 
destination in parallel.

As far as I got it append_branch() should not be called any more in 
failure route unless parallel forking is desired. This is great, the 
only issue is that this is not mentioned in the documentation, the tm 
readme file still contains the old examples, and all the configurations 
under etc/ still call append_branch(). Is there any plan to update the 
docs and configs before releasing the new sip-router version?

Thanks,
Miklos
