The script has set -u so calling do-rebase --help fails with the following:
$ ./do-rebase --help
./do-rebase: line 16: $1: unbound variable
Avoid this by setting a default value when doing the parameter expansion
for the positional parameter $1 passed to the usage() function.

The do-rebase script generate patches with git-format-patch, but the pkg
expects some non-default git configurations for the diffs and stats.
So instead requiring developers to setup these config options, pass them
to git-format-patch in do-rebase to generate the proper patches.
