Since you never use the value stored in "$DOTEST/upstream" for anything
else anyway, how about doing something like this instead? It would make
the meaning of the file used as a state variable much clearer.
It may break hooks and outside scripts that look at $DOTEST/upstream. I
didn't check.
The hunk in the middle is to protect you against an environment variable
UPSTREAM the user may have before starting "rebase -i". There could be
other state variables you added in recent commit d911d14 (rebase -i: learn
to rebase root commit, 2009-01-02) that needs similar protection. Please
check.
