Recent changes to --fixup, adding amend suboption, caused the
--edit flag to be ignored as use_editor was always set to zero.

Restore edit_flag having higher priority than fixup_message when
deciding the value of use_editor by moving the edit flag condition
later in the method.

This version looks good, thanks for revising it

Best Wishes

     commit: restore --edit when combined with --fixup
Recent changes to --fixup, adding amend suboption, caused the --edit
     flag to be ignored as use_editor was always set to zero.
Restore edit_flag having higher priority than fixup_message when
     deciding the value of use_editor by only changing the default if
     edit_flag is not set.
Changes since v1: Added test verifying that --fixup --edit brings up
     editor.
Changes since v2: Clarify if condition and use write_script helper in
     test.
Changes since v3: Simplify test. Changes since v4: Using cleaner fix by Phillip Wood instead and added an
     explicit verification to a test for --fixup without --edit.
