run-tests: fix python executable detection and copy on Windows

changelog: don't use generaldelta

revlog: get rid of defversion defversion was a property (later option) on the store opener, used to propagate the changelog revlog format to the other revlogs, so they would be created with the same format. This required that the changelog instance was created before any other revlog; an invariant that wasn't directly enforced (or documented) anywhere. We now use the revlogv1 requirement instead, which is transfered to the store opener options. If this option is missing, v0 revlogs are created.

bash_completion: Use "hg paths -q" instead of piping through sed

paths: Add support for -q/--quiet Suppresses output (resolved paths or "not found!") when searching a path, similar to "grep -q". Sample usage: hg paths -q foo || echo "there is no foo" Just prints path names (instead of "name = result") when listing all path definitions, like "hg bookmarks -q". Sample usage: hg paths -q | while read i; do hg incoming "$i"; done
