Issues that need to be resolved before 1.7.0-rc1

Right now 'next' is empty and there are a handful topics in 'pu':

 - Jens Lehmann's updates to omit expensive is_submodule_modified() call
   when running "diff --ignore-submodules" and to make "diff --submodule"
   to show the "dirty worktree" status.  I think they should be in 1.7.0
   as part of the series to show work tree/index dirtiness in "git diff"
   output from the superproject.

 - Christian Couder's "reset --keep".  I am inclined to exclude it from
   1.7.0 as I cannot make a convincing argument to sell this to users
   without confusing them (even I am not convinced even though I do fairly
   straight line development at day-job), but hopefully we can keep
   cooking it in 'pu/next'.

 - Johan Herland's notes updates.  Won't be ready for 1.7.0 but hopefully
   we can keep cooking in 'pu/next'.

 - John Hawley's gitweb caching layer.  Jakub is splitting them into
   smaller pieces and they are still generating discussions.

 - My "how about this" patch to make 'grep --author=foo --grep=bar' to
   implicitly run --all-match; this is not yet readyand needs reworking.

There also is a discussion on //server/share path on msysgit, that was
started since 288123f (ignore duplicated slashes in make_relative_path(),
2010-01-21).  If that commit _breaks_ use case on msysgit that used to
work, I think the sanest course of action is to revert it and ship 1.7.0
with the same breakage we've had forever when the user gives extra slashes
in the paths to --git-dir or --work-tree options.  We could instead apply
Thomas's patch

Message-ID: [ref]

that changed behaviour in much narrower case, which should be safer.  In
any case, a more intrusive change for UNC is outside the scope of 1.7.0
(discussion and preparation can continue on 'pu/next').

I saw a few patches and discussion to git-p4 in contrib from Pal-Kristian
Engstad and I understand that we are waiting for revised version before I
should take any action on them.

The above are the current set of unresolved topics and their status but I
am sure I've missed some others.  Please remind me and the list if there
are other important ones that need to be discussed.
