template: add shortest(node) template function Adds a '{shortest(node)}' template function that results in the shortest hex node that uniquely identifies the changeset at that time. The minimum length can be specified as an optional second argument and defaults to 4. This is useful for producing prettier log output, like so: @ durham shortestnode | 77cf template: add pad function for padding output | o durham | b183 template: add shortestnode keyword | o pierre-yves @ | 6545 backout: add a message after backout that need manual commit | | o durham manifestcache |/ 93f0 manifest cache | | o durham catperf | | c765 cat: increase perf when catting single files | | | o durham |/ 9c53 changectx: increase perf of walk function |

revset: added intersection to baseset class Added the method __and__ to the baseset class to be able to intersect with other objects in a more efficient way.

revset: added substraction to baseset class Added __sub__ method to the baseset class to be able to compare it with other subsets more efficiently.

revset: implemented set caching for revset evaluation Added set caching to the baseset class. It lazily builds the set whenever it's needed and keeps a reference which is returned when the set is requested instead of being built again.

revset: added baseset class (still empty) to improve revset performance This class is going to be used to cache the set that is created from this list in many cases while evaluating a revset.
