And in cvs, one would just do: cvs diff -r GCC_4_0_BRANCH file.c

In cvs: cvs diff -r GCC_4_0_BRANCH -r GCC_3_4_BRANCH file.c

Now consider how this scales as the last part (after the branch name)
changes from the relatively simple "gcc/file.c" to something more
complex like "gnu/dist/gcc/gcc/fixinc/tests/base/arch/i960/archI960.h"
(a real example from the NetBSD CVS repository). Even the proposed "+"
syntax doesn't buy you much.
