debug: make debug{revlog,index,data} --dir not just a flag The directory argument (for tree manifests) should belong to to the --dir argument. I had mistakenly made --dir a flag. One effect of this was that I had meant for "-m" to be optional, but instead it changed the behavior of --dir, so with "hg debugdata -m --dir dir1 0", the -m took over and the "dir1" got treated as a revision in the root manifest log.
