When we run a regular "git fetch" without arguments, we
update the tracking refs according to the configured
refspec. However, when we run "git fetch origin master" (or
"git pull origin master"), we do not look at the configured
refspecs at all, and just update FETCH_HEAD.
We miss an opportunity to update "refs/remotes/origin/master"
(or whatever the user has configured). Some users find this
confusing, because they would want to do further comparisons
against the old state of the remote master, like:
$ git pull origin master
$ git log HEAD...origin/master
In the currnet code, they are comparing against whatever
commit happened to be in origin/master from the last time
they did a complete "git fetch". This patch will update a
ref from the RHS of a configured refspec whenever we happen
to be fetching its LHS. That makes the case above work.
The downside is that any users who really care about whether
and when their tracking branches are updated may be
surprised.

Each "struct ref" has a boolean flag that is set by the
fetch code to determine whether the ref should be marked as
"not-for-merge" or not when we write it out to FETCH_HEAD.
It would be useful to turn this boolean into a tri-state,
with the third state meaning "do not bother writing it out
to FETCH_HEAD at all". That would let us add extra refs to
the set of refs to be stored (e.g., to store copies of
things we fetched) without impacting FETCH_HEAD.
This patch turns it into an enum that covers the tri-state
case, and hopefully makes the code more explicit and easier
to read.

The documentation erroneously used the same wording for both fetch and
pull, stating that something will be merged even in git-fetch(1).

We have three sequential tests for for whether tracking refs
are updated by various fetches and pulls; the first two
should not update the ref, and the third should. Each test
depends on the state left by the test before.
This is fragile (a failing early test will confuse later
tests), and means we cannot add more "should update" tests
after the third one.
Let's instead save the initial state before these tests, and
then reset to a known state before running each test.

The drop-down lists used for things like the criteria for finding
commits (containing/touching paths/etc.) use a combobox if we are
using the ttk widgets. By default the combobox exports its value
as the selection when it is changed, which is unnecessary, and sometimes
the combobox wouldn't release the selection, which is annoying.
To fix this, we make these comboboxes not export their selection,
and also clear their selection whenever they are changed. This makes
them more like a simple selection of alternatives, improving the look
and feel of gitk.

Test 2 of t5004 checks if a supposedly empty tar archive really
contains no files. 24676f02 (t5004: fix issue with empty archive test
and bsdtar) removed our commit hash to make it work with bsdtar, but
the test still fails on NetBSD and OpenBSD, which use their own tar
that considers a tar file containing only NULs as broken.
Here's what the different archivers do when asked to create a tar
file without entries:
$ uname -v
NetBSD 6.0.1 (GENERIC)
$ gtar --version | head -1
tar (GNU tar) 1.26
$ bsdtar --version
bsdtar 2.8.4 - libarchive 2.8.4
$ : >zero.tar
$ perl -e 'print "\0" x 10240' >tenk.tar
$ sha1 zero.tar tenk.tar
SHA1 (zero.tar) = da39a3ee5e6b4b0d3255bfef95601890afd80709
SHA1 (tenk.tar) = 34e163be8e43c5631d8b92e9c43ab0bf0fa62b9c
$ : | tar cf - -T - | sha1
da39a3ee5e6b4b0d3255bfef95601890afd80709
$ : | gtar cf - -T - | sha1
34e163be8e43c5631d8b92e9c43ab0bf0fa62b9c
$ : | bsdtar cf - -T - | sha1
34e163be8e43c5631d8b92e9c43ab0bf0fa62b9c
So NetBSD's native tar creates an empty file, while GNU tar and bsdtar
both give us 10KB of NULs -- just like git archive with an empty tree.
Now let's see how the archivers handle these two kinds of empty tar
files:
$ tar tf zero.tar; echo $?
tar: Unexpected EOF on archive file
1
$ gtar tf zero.tar; echo $?
gtar: This does not look like a tar archive
gtar: Exiting with failure status due to previous errors
2
$ bsdtar tf zero.tar; echo $?
0
$ tar tf tenk.tar; echo $?
tar: Cannot identify format. Searching...
tar: End of archive volume 1 reached
tar: Sorry, unable to determine archive format.
1
$ gtar tf tenk.tar; echo $?
0
$ bsdtar tf tenk.tar; echo $?
0
NetBSD's tar complains about both, bsdtar happily accepts any of them
and GNU tar doesn't like zero-length archive files. So the safest
course of action is to stay with our block-of-NULs format which is
compatible with GNU tar and bsdtar, as we can't make NetBSD's native
tar happy anyway.
We can simplify our test, however, by taking tar out of the picture.
Instead of extracting the archive and checking for the non-presence of
files, check if the file has a size of 10KB and contains only NULs.
This makes t5004 pass on NetBSD and OpenBSD.

Add a test to verify the emptiness of an archive by extracting its
contents. Don't run this test if the version of tar doesn't support
archives containing only a comment header, though.
The existing check 'tar archive of empty tree is empty' used to work
like that (minus the tar capability check) but was changed to depend
on the exact representation of empty tar files created by git archive
instead of on the behaviour of tar in order to avoid issues with
different tar versions.
The different approaches test different things: The existing one is
for empty trees, for which we know the exact expected output and thus
we can simply check it without extracting; the new one is for commits
with empty trees, whose archives include stamps and so the more
"natural" check by extraction is a better fit because it focuses on
the interesting aspect, namely the absence of any archive entries.

git-merge-tree causes a null pointer dereference when a directory

When this happens, we want to handle the entry as a directory and not

in the directory mask when the entry is missing or when it is a
directory, only performing the file comparison when we know that a file
