    rebase [-i --exec | -ix] <cmd>...
....
    Tests about this new command are also added in t3404-rebase-interactive.sh.
....


This test doesn't pass on my Mac Os box.

I run it with --debug --verbose, and it looks like another sed problem on Mac OS, may be.
(My sed is /usr/bin, Mac OS X 10.6.8)

I haven't been able to dig very deep into this, but the line  
"sed: 1: "/^pick .*/i\t\t\t\texec  gi ...": command i expects \ followed by text"
looks suspicious.

Could the same be achieved by using tail instead of sed?
Anybody else having this problem?
