Subject: format-patch: use same number of digits in numbers
X-Git-Tag: v0.99.9m^2~3
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=7564577a6c05a1153ddb94cbe68e75c391b52f20;p=git.git

format-patch: use same number of digits in numbers

This would help sorting by subject in MUA work saner even though
MUA is too dumb to attempt sorting numbered subjects sanely.
