revset: filter first/last members by __and__ operation...

revset: filter first/last members by __and__ operation This replaces 'if y in subset' with '& subset'. first(null) and last(wdir()) are fixed thanks to fullreposet.__and__. This also revealed that first() and last() don't follow the order of the input set. 'ls & subset' is valid only if the ordering requirement is 'define' or 'any'. No performance regression observed: revset : limit(0:9999, 100, 9000) 0) 0.001164 1) 0.001135 revset : 9000 & limit(0:9999, 100, 9000) 0) 0.001224 1) 0.001181 revset : last(0:9999, 100) 0) 0.000237 1) 0.000199
