Date: Wed, 9 Jan 2013 12:23:35 +0000 Subject: seq: fix misaligment with -w when no precision for start value * src/seq.c (get_default_format): Also account for the case where '.' is auto added to the start value, which is significant when the number sequence narrows. * tests/misc/seq.pl: Add two new tests for the failing cases. * NEWS: Mention the fix.
