Bad number of digits in brace sequence expansion when used increment

[Roman Rakus]

When we use 0 prefix and increment bash will prefix all integers with 
bad number of zeroes. Man page says "When either x or y begins with a 
zero, the shell attempts to force all generated terms to contain the 
same number of digits, zero-padding where necessary."
The number of digits is same, but not what would anyone expect.
Repeated by:
echo {1..05..1}

Actual result:
00001 00002 00003 00004 00005

Desired result:
01 02 03 04 05

Patch included.
