[Reviewers] Need some cross-reviews: help?

[Augie Fackler]

In particular, these changes from martinvonz that I reviewed:

o  58e7 martinvonz augie
|  copies: handle more cases where a file got replaced by a copy
o  4b79 martinvonz augie
|  tests: test more cases where a file got replaced by a copy

and

o  0991 martinvonz augie
|  fix: only check for obsolete commits in the --rev case
o  136a martinvonz augie
|  fix: don't include obsolete descendants with -s
o  15a9 martinvonz augie
|  tests: add test showing how `hg fix -s` deals with obsolete and orphan nodes
o  f909 martinvonz augie
|  fix: suggest --source instead of --rev on empty revset

If there's a problem with those that's preventing them from getting accept stamps, please speak up: I don't want to get too far ahead of those changes in draft phase, and it's already starting to get pretty deep.

Thanks!
