I got there in the end with
./configure CPPFLAGS='-I/usr/local/Cellar/libxml2/2.7.7/include
-I/usr/local/Cellar/readline/6.1/include'
LDFLAGS='-L/usr/local/Cellar/libxml2/2.7.7/lib
-L/usr/local/Cellar/readline/6.1/lib'

So I don't think the patch is really needed.

What would be good though is a AC_CHECK_LIB(readline, rl_completion_matches
This would work with readline 4.2 and higher, and fail on Leopard
since the readline shim libedit provides doesn't do completion.

As soon as I can do a proper bootstrap from git...
