git latest master: a6828f536119c3288b0be772e3870f1a464d017d -- error in t3404-rebase-interactive.sh on Solaris

looks like the grep located in /usr/bin has a problem. When I put the XPG4 earlier on my bath than /usr/bin this test passes. So, this is not strictly a bug, but I'm sure a lot of Solaris users out there have /usr/bin earlier than XPG4, so it's probably something you should be aware of.
