ValueError: invalid literal for int() with base 10: 'rc1'

alex@evisceration:~/android$ git --version
git version 1.9.rc1

it uses "rc1" as an int and therefore breaks.

a similar issue is reported here too, which affects another formatting.

formatting of this issue: x.x.rc
formatting of the similar issue: x.x.x-rc
