"git status" carefully names a detached HEAD "at" resp. "from" a rev or
ref depending on whether the detached HEAD has moved since. "git branch"
always uses "from", which can be confusing, because a status-aware user
would interpret this as moved detached HEAD.
Make "git branch" use the same logic and wording.

In cat_one_file(), "type" and "size" variables are defined in the
function scope, and then two variables of the same name are defined
in a block in one of the if/else statement, hiding the definitions
in the outer scope.
Because the values of the outer variables before the control enters
this scope, however, do not have to be preserved, we can remove
useless definitions of variables from the inner scope safely without
breaking anything.

The code handling %(upstream:track) and %(upstream:trackshort)
assumed that it always had a valid branch that had been sanitized
earlier in populate_value(), and thus did not check the return value
of the call to stat_tracking_info().
While there is indeed some sanitization code that basically
corresponds to stat_tracking_info() returning 0 (no base branch
set), the function can also return -1 when the base branch did exist
but has since then been deleted.
In this case, num_ours and num_theirs had undefined values and a
call to `git for-each-ref --format="%(upstream:track)"` could print
spurious values such as
[behind -111794512]
[ahead 38881640, behind 5103867]
even for repositories with one single commit.
Verify stat_tracking_info()'s return value and do not print anything
if it returns -1. This behavior also matches the documentation ("has
no effect if the ref does not have tracking information associated
with it").

Earlier we made "rev-list --object-edge" more aggressively list the
objects at the edge commits, in order to reduce number of objects
fetched into a shallow repository, but the change affected cases
other than "fetching into a shallow repository" and made it
unusably slow (e.g. fetching into a normal repository should not
have to suffer the overhead from extra processing). Limit it to a
more specific case by introducing --objects-edge-aggressive, a new
option to rev-list.

- "exec_cmd.h" became unnecessary at b931aa5a (Call builtin ls-tree
in git-cat-file -p, 2006-05-26), when it changed an earlier code
that delegated tree display to "ls-tree" via the run_command()
API (hence needing "exec_cmd.h") to call cmd_ls_tree() directly.
We should have removed the include in the same commit, but we
forgot to do so.
- "diff.h" was added at e5fba602 (textconv: support for cat_file,
2010-06-15), together with "userdiff.h", but "userdiff.h" can be
included without including "diff.h"; the header was unnecessary
from the beginning.
- "tag.h" and "tree.h" were necessary since 8e440259 (Use blob_,
commit_, tag_, and tree_type throughout., 2006-04-02) to check
the type of object by comparing typename with tree_type and
tag_type (pointers to extern strings).
21666f1a (convert object type handling from a string to a number,
2007-02-26) made these <type>_type strings unnecessary, and it
could have switched to include "object.h", which is necessary to
use typename(), but it forgot to do so. Because "tag.h" and
"tree.h" include "object.h", it did not need to explicitly
include "object.h" in order to start using typename() itself.
We do not even have to include "object.h" after removing these
two #includes, because "builtin.h" includes "commit.h" which in
turn includes "object.h" these days. This happened at 7b9c0a69
(git-commit-tree: make it usable from other builtins,
2008-07-01).

The get_merge_bases*() API was easy to misuse by careless

needed to be traversed.
* jc/merge-bases:
get_merge_bases(): always clean-up object flags

The parse_options API expects an array of alternative usage lines
to which it automatically ads the language-appropriate "or" when
displaying. Each of these options is marked for translation with N_
and then later translated when gettext is called on each element
of the array.
Since the N_ macro just expands to its argument, if two N_-marked
strings appear next to each other without being separated by anything
else such as a comma, the preprocessor will join them into one string.
In that case two separate strings get marked for translation, but at
runtime they have been joined into a single string passed to gettext
which then fails to get translated because the combined string was
never marked for translation.
Fix this by properly separating the two N_ marked strings with
a comma and removing the embedded "\n" and " or:" that are
properly supplied by the parse_options API.

checkout-index --temp only properly prints relative paths which are
descendants of the current directory. Paths in ancestor or sibling
directories (or their children) are often printed in mangled form. For
example:
mkdir a bbb &&
>file &&
>bbb/file &&
git update-index --add file bbb/file &&
cd a &&
git checkout-index --temp ../file ../bbb/file
prints:
.merge_file_ooblek le
.merge_file_igloo0 b/file
rather than the correct:
.merge_file_ooblek ../file
.merge_file_igloo0 ../bbb/file
Internally, given the above example, checkout-index prefixes each input
argument with the name of the current directory ("a/", in this case),
and then assumes that it can simply skip forward by strlen("a/") bytes
to recover the original name. This works for files in the current
directory or its descendants, but fails for files in ancestors or
siblings (or their children) due to path normalization.
For instance, given "../file", "a/" is prepended, giving "a/../file".
Path normalization folds out "a/../", resulting in "file". Attempting
to recover the original name by skipping strlen("a/") bytes gives the
incorrect "le" rather than the desired "../file".
Fix this by taking advantage of write_name_quoted_relative() to recover
the original name properly, rather than assuming that it can be
recovered by skipping strlen(prefix) bytes.
As a bonus, this also fixes a bug in which checkout-index --temp
accessed and printed memory beyond the end-of-string. For instance,
within a subdirectory named "subdirectory", and given argument
"../file", prefixing would give "subdirectory/../file", which would
become "file" after normalization. checkout-index would then attempt to
recover the original name by skipping strlen("subdirectory/") bytes of
"file", which placed it well beyond end-of-string. Despite this error,
it often appeared to give the correct result, but only due to an
accident of implementation which left an apparently correct copy of the
path in memory following the normalized value. In particular, handed
"subdirectory/../file", in-place processing by normalize_path_copy_len()
resulted in "file\0rectory/../file". When checkout-index skipped
strlen("subdirectory/") bytes, it ended up back at "../file" and thus
appeared to give the correct answer, despite being past end-of-string.

When fetching into or pushing from a shallow repository, we want to
aggressively mark edges as uninteresting, since this decreases the pack
size. However, aggressively marking edges can negatively affect
performance on large non-shallow repositories with lots of refs.
Teach pack-objects a --shallow option to indicate that we're pushing
from or fetching into a shallow repository. Use
--objects-edge-aggressive only for shallow repositories and otherwise
use --objects-edge, which performs better in the general case. Update
the callers to pass the --shallow option when they are dealing with a
shallow repository.

In commit fbd4a70 (list-objects: mark more commits as edges in
mark_edges_uninteresting - 2013-08-16), we marked an increasing number
of edges uninteresting. This change, and the subsequent change to make
this conditional on --objects-edge, are used by --thin to make much
smaller packs for shallow clones.
Unfortunately, they cause a significant performance regression when
pushing non-shallow clones with lots of refs (23.322 seconds vs.
4.785 seconds with 22400 refs). Add an option to git rev-list,
--objects-edge-aggressive, that preserves this more aggressive behavior,
while leaving --objects-edge to provide more performant behavior.
Preserve the current behavior for the moment by using the aggressive
option.

When adding a remote, we make sure that the remote does not exist
already. However, this test was not quite correct: when the
url.<...>.insteadOf config variable was set to the remote name to be
added, the code would assume that the remote exists already.
Let's allow adding remotes when there is a url.<...>.insteadOf setting
when both the name and the URL agree with the remote to be added.
It might seem like a mistake to compare against remote->url[0] without
verifying that remote->url_nr >=1, but at this point a missing URL has
been filled by the name already, therefore url_nr cannot be zero.
