New Monitor option to specify minimum percentage width
Ignore-this: 5e0413c218f257c0db06f83665bd2e5 The new option, -p, is a number specifying how many characters the numerical part of percentages should take. Padding consists of whitespace. E.g. -p 3 makes '3%' appear as ' 3%'. The default value is 0, which means padding is disabled. darcs-hash:20100120215608-40885-2c2ac6718af740971dad491eea92947bae840163.gz
