Can't make mrb gitCheckout --fork work

[PetrilloAtWork]

mrb gitCheckout has a --fork option that should create a user fork in GitHub as needed, and set up the GIT remotes accordingly.

But I can't make it work:

mrb g --dry-run --fork icaruscode

only says it will check out the repository, no mention of forking (and without --dry-run, it will only check out):

INFO: would execute command git clone [email protected]:SBNSoftware/icaruscode.git icaruscode
INFO: Would update CMakeLists.txt for checked-out repository icaruscode

Peeking at the code, it looks like forking is attempted only if there is some post-processing stage registered in MRB, which happens only for the Fermilab Redmine repositories. My my PERL is (proudly) rusty, so I might be missing the point.

What is the correct way to use this feature?

This should be labelled "Support", but as a user I can't assign labels (including the "high priority" mentioned in the template issue, incidentally).
