git status: skip empty directories, and add -u to show all untracked files
By default, we use --others --directory to show uninteresting
directories (to get user's attention) without their contents (to
unclutter output). Showing empty directories do not make sense,
so pass --no-empty-directory when we do so.
Giving -u (or --untracked) disables this uncluttering to let the
user get all untracked files.

GIT-VERSION-GEN can incorrectly return a default version of

Convert these to "git cmd" format so that a proper answer is

Libify the index refresh logic
This cleans up and libifies the "git update-index --[really-]refresh"

"commit" and "status" commands as built-ins.
It really just moves "refresh_index()" from update-index.c to
read-cache.c, but it also has to change the calling convention so that the
function uses a "unsigned int flags" argument instead of various static
flags variables for passing down the information about whether to be quiet

Provide a way to flush git-diff-tree's output
Gitk wants to use git-diff-tree as a filter to tell it which ids from
a given list affect a set of files or directories. We don't want to
fork and exec a new git-diff-tree process for each batch of ids, since
there could be a lot of relatively small batches. For example, a
batch could contain as many ids as fit in gitk's headline display
window, i.e. 20 or so, and we would be processing a new batch every
time the user scrolls that window.
The --stdin flag to git-diff-tree is suitable for this, but the main
difficulty is that the output of git-diff-tree gets buffered and
doesn't get sent until the buffer is full.
This provides a way to get git-diff-tree to flush its output buffers.

deep base objects in try_delta() to mitigate that bad behavior.
This patch adjust the MAX_size allowed for a delta based on the depth of
the base object as well as enabling the early eviction of max depth
objects from the object window. When used separately, those two things
produce slightly better and much worse results respectively. But their
combined effect is a surprising significant packing improvement.
