[sup-devel] [PATCH] ruby 1.9: expect nil start_offset when an MBox::Loader is first created

[Rich Lane <rlane@club.cc.cmu.edu>]

Various callers (including sup-add) passed a nil start_offset. Through a
convoluted path probably involving the fact that nil.to_i == 0, this did the
right thing on Ruby 1.8. It crashes on 1.9, so change initialize to expect a
nil offset and replace it with 0.
