Please try to be a bit less cryptic. Which exact parts (lines) of the
code are you referring to?

I can neither find any references to "branch  1"  or  "branch  2"  or
"future code" or anything like that in the whole source tree.

We are all agreed that your  theory  is  crazy.  The  question  which
divides  us  is  whether it is crazy enough to have a chance of being
correct. My own feeling is that it is not crazy enough.  - Niels Bohr
