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.
