With the above change use_editor no longer defaults to 0 for --fixup as
it used to do.
My expected behavior (based on old versions):
git commit --fixup <hash>  /// No editor
git commit --fixup <hash> --edit  /// Editor
As far as I can see your change would display an editor in both cases.

An alternative would be:
+       if (logfile || have_option_m || use_message || fixup_message)
+               use_editor = 0;
+       if (0 <= edit_flag)
+               use_editor = edit_flag;

That would fix the above cases but in 
"commit: add amend suboption to --fixup to create amend! commit"
the implementation left
git commit --fixup amend:<hash>  // Editor
and I didn't want to change that. But if the default should be no editor
here as well then the above would be a better patch.
