Commit 43662b23ab (format-patch: keep cover-letter diffstat wrapped in
72 columns - 2018-01-24) uncondtionally sets stat width to 72 when
generating diffstat for the cover letter, ignoring --stat from command
line. But it should only do so when stat width is still default
(i.e. stat_width == 0).

In order to fix this, we should only set stat_width if stat_width is
zero. But it will never be. Commit 071dd0ba43 (format-patch: reduce
patch diffstat width to 72 - 2018-02-01) makes sure that default stat
width will be 72 (ignoring $COLUMNS, but could still be overriden by
--stat). So all we need to do here is drop the assignment.

* This submission should have been posted as v3, not v2. V2 was posted at

https://public-inbox.org/git/20181107164953.24965-1-pclouds@gmail.com/

* Comparing the patch emails, the only difference is that this version
renames "expect.40" to "expect.60". This should have been mentioned in a
cover letter, or in the Notes section of the current submission.

* In my response to the (original) v2 posting, at

https://public-inbox.org/git/f0f95dd0-1a9e-01d0-70f4-3c6d5450df70@redhat.com/

I stated that I didn't try to run the test suite, and gave my T-b (under
the circumstances described there). Given that the change in v3 (= this
submission) is limited to the test case, I think my T-b should have been
carried forward.

Thanks
Laszlo
