After commit cbfd5e1c ("drop some obsolete "x = x" compiler warning
hacks", 21-03-2013) removed a gcc specific hack, older versions of
gcc now issue an "'contents' might be used uninitialized" warning.
In order to suppress the warning, we simply initialize the variable
to NULL in it's declaration.

Commit cbfd5e1c ("drop some obsolete "x = x" compiler warning hacks",
21-03-2013) removed a gcc hack that suppressed an "might be used
uninitialized" warning issued by older versions of gcc.
However, commit 3aa99df8 ('fast-import: clarify "inline" logic in
file_change_m', 21-03-2013) addresses an (almost) identical issue
(with very similar code), but includes additional code in it's
resolution. The solution used by this commit, unlike that used by
commit cbfd5e1c, also suppresses the -Wuninitialized warning on
older versions of gcc.
In order to suppress the warning (against the 'oe' symbol) in the
note_change_n() function, we adopt the same solution used by commit 3aa99df8.

There was no Porcelain way to say "I no longer am interested in
this submodule", once you express your interest in a submodule with
"submodule init". "submodule deinit" is the way to do so.
The "--match=<pattern>" option of "git describe", when used with
"--all" to allow refs that are not annotated tags to be used as a
base of description, did not restrict the output from the command
to those that match the given pattern.
We may want to have a looser matching that does not restrict to tags,
but that can be done as a follow-up topic; this step is purely a bugfix.

merge-one-file: force content conflict for "both sides added" case
Historically, we tried to be lenient to "both sides added, slightly
differently" case and as long as the files can be merged using a
made-up common ancestor cleanly, since f7d24bbefb06 (merge with
/dev/null as base, instead of punting O==empty case, 2005-11-07).
This was later further refined to use a better made-up common file
with fd66dbf5297a (merge-one-file: use empty- or common-base
condintionally in two-stage merge., 2005-11-10), but the spirit has
been the same.
But the original fix in f7d24bbefb06 to avoid punting on "both sides
added" case had a code to unconditionally error out the merge. When
this triggers, even though the content-level merge can be done
cleanly, we end up not saying "content conflict" in the message, but
still issue the error message, showing "ERROR: in <pathname>".
Move that "always fail for add/add conflict" logic a bit higher to
fix this.
transport.c: help gcc 4.6.3 users by squelching compiler warning
To a human reader, it is quite obvious that cmp is assigned before
it is used, but gcc 4.6.3 that ships with Ubuntu 12.04 is among
those that do not get this right.
The "funny filename" comment was from b539c5e8fbd3 (git-merge-one:
new merge world order., 2005-12-07) where the removed code just
before that new comment ended with:
merge "$4" "$orig" "$src2"
(yes, we used to use "merge" program from the RCS suite). The
comment refers to one of the bad side effect the old code used to
have and warns against such a practice, i.e. it was talking about
the code that no longer existed.
t7600: use test_config to set/unset git config variables
Instead of using construct such as:
test_when_finished "git config --unset <key>"
git config <key> <value>
uses
test_config <key> <value>
The latter takes care of removing <key> at the end of the test.
Tests are modified to assume default configuration at entry,
and to reset the modified configuration variables at the end.
Test 'merge log message' was relying on the presence of option `--no-ff`
in the configuration. With the option, git show -s --pretty=format:%b HEAD
produces an empty line and without the option, it produces an empty file.
The test is modified to check with and without `--no-ff` option.

fread returns the number of items read, with no special error return.
Commit 98f85ff (reflog: add for_each_reflog_ent_reverse() API -
2013-03-08) introduced a call to fread which checks for an error with
"nread < 0" which is tautological since nread is unsigned. The correct
check in this case (which tries to read a single item) is "nread != 1".

Logic in still_interesting function allows to stop the commits
traversing if the oldest processed commit is not older then the
youngest commit on the list to process and the list contains only
commits marked as not interesting ones. It can be premature when dealing
with a set of coequal commits. For example git rev-list A^! --not B
provides wrong answer if all commits in the range A..B had the same
commit time and there are more then 7 of them.
To fix this problem the relevant part of the logic in still_interesting
is changed to: the walk can be stopped if the oldest processed commit is
younger then the youngest commit on the list to processed.

When asking Git to merge a tag (such as a signed tag or annotated tag),
it will always create a merge commit even if fast-forward was possible.
It's like having --no-ff present on the command line.
It's a difference from the default behavior described in git-merge.txt.
It should be documented as an exception of "FAST-FORWARD MERGE" section
and "--ff" option description.

wt-status: fix possible use of uninitialized variable
In wt_status_print_change_data, we accept a change_type flag
that is meant to be either WT_STATUS_UPDATED or
WT_STATUS_CHANGED. We then switch() on this value to set
the local variable "status" for each case, but do not
provide a fallback "default" label to the switch statement.
As a result, the compiler realizes that "status" might be
unset, and complains with a warning. To silence this
warning, we use the "int status = status" trick. This is
correct with the current code, as all callers provide one of
the two expected change_type flags. However, it's also a
maintenance trap, as there is nothing to prevent future
callers from passing another flag, nor to document this
assumption.
Instead of using the "x = x" hack, let's handle the default
case in the switch() statement with a die("BUG"). That tells
the compiler and any readers of the code exactly what the
function's input assumptions are.
We could also convert the flag to an enum, which would
provide a compile-time check on the function input. However,
since these flags are part of a larger enum, that would make
the code unnecessarily complex (we would have to make a new
enum with just the two flags, and then convert it to the old
enum for passing to sub-functions).
