Merge branch 'bc/fetch-thin-less-aggressive-in-normal-repository'

Earlier we made "rev-list --object-edge" more aggressively list the objects at the edge commits, in order to reduce number of objects fetched into a shallow repository, but the change affected cases other than "fetching into a shallow repository" and made it unusably slow (e.g. fetching into a normal repository should not have to suffer the overhead from extra processing). Limit it to a more specific case by introducing --objects-edge-aggressive, a new option to rev-list. * bc/fetch-thin-less-aggressive-in-normal-repository: pack-objects: use --objects-edge-aggressive for shallow repos rev-list: add an option to mark fewer edges as uninteresting Documentation: add missing article in rev-list-options.txt
