Any unambiguous prefix of a command dispatches (zit up, zit tim); an ambiguous one names its candidates; an exact verb always wins, so stat stays the store census. Aliases: ci/checkin, co/checkout, changes, delete/forget/ remove, rename, blame/praise, new. A token of three letters or fewer is only suggested at edit distance 1, and an unknown verb prints two lines, never the command list. Closes zit#156. check-in: e114f7a174 user: dmestas tags: trunk
