Move commit distance computation into a separate bash script.

[rolfbjarne]

The script does the same thing, except:

• It doesn't use 'bc', but instead bash's intrinsic math support: '$((1+2))' -
  because when we execute in bash on Windows, 'bc' might not be available.
• It's easier to debug.

This fixes a problem when we need to compute these values on Windows in CI.
