Change `while(<$fh>) { my $c = $_' to `while(my $c = <$fh>) {', and
use `chomp $c' instead of `$c =~ s/\n$//g;', the two are equivalent in
this case.
I've also changed the --cccmd test so that we test for the stripping
of whitespace at the beginning of the lines returned from the
--cccmd. I think we probably shouldn't do this, but it was there
already so I haven't changed the behavior.

Change the use of Sys::Hostname from a "use" to a "require". The

It's a minor annoyance when you take the painstaking time to setup To:
headers for each patch in a large series, and then go out to send the
series with git-send-email and watch git ignore the To: headers in the
patch files.
Therefore, always add To: headers from a patch file to the To: headers
for that message. Keep the prompt for the blanket To: header so as to
not break scripts (and user expectations). This means even if a patch
has a To: header, git will prompt for the To: address. Otherwise, we'll
need to introduce interface breakage to either request the header for
each patch missing a To: header or default the header to whatever To:
address is found first (be it in a patch or from user input). Both of
these options don't seem very obvious/useful.

repack: add -F flag to let user choose between --no-reuse-delta/object
In 479b56ba ('make "repack -f" imply "pack-objects --no-reuse-object"'),
git repack -f was changed to include recompressing all objects on the
zlib level on the assumption that if the user wants to spend that much
time already, some more time won't hurt (and recompressing is useful if
the user changed the zlib compression level).
However, "some more time" can be quite long with very big repositories,
so some users are going to appreciate being able to choose. If we are
going to give them the choice, --no-reuse-object will probably be
interesting a lot less frequently than --no-reuse-delta. Hence, this
reverts -f to the old behaviour (--no-reuse-delta) and adds a new -F
option that replaces the current -f.

indicate a 17% decrease in time being made available to users:

perl: bump the required Perl version to 5.8 from 5.6.[21]
Formalize our dependency on perl 5.8, bumped from 5.6.[12]. We already
used the three-arg form of open() which was introduced in 5.6.1, but
t/t9700/test.pl explicitly depended on 5.6.2.
However git-add--interactive.pl has been failing on the 5.6 line since
it was introduced in v1.5.0-rc0~12^2~2 back in 2006 due to this open
syntax:
sub run_cmd_pipe {
my $fh = undef;
open($fh, '-|', @_) or die;
return <$fh>;
}
Which when executed dies on "Can't use an undefined value as
filehandle reference". Several of our tests also fail on 5.6 (even
more when compiled with NO_PERL_MAKEMAKER=1):
Our code is bitrotting on 5.6 with no-one interested in fixing it, and
pinning us to such an ancient release of Perl is keeping us from using
useful features introduced in the 5.8 release.
The 5.6 series is now over 10 years old, and the 5.6.2 maintenance
release almost 7. 5.8 on the other hand is more than 8 years old.
All the modern Unix-like operating systems have now upgraded to it or
a later version, and 5.8 packages are available for old IRIX, AIX
Solaris and Tru64 systems.

CodingGuidelines: spell Arithmetic Expansion with $(($var))
POSIX wants shells to support both "N" and "$N" and requires them to yield
the same answer to $((N)) and $(($N)), but we should aim for portability
in a case like this, especially when the price we pay to do so is so
small, i.e. a few extra dollars.
t1503: Fix arithmetic expansion syntax error when using dash
On systems which have dash as /bin/sh, such as Ubuntu, the final
test (master@{n} for various n) fails with a syntax error while
processing an arithmetic expansion. The syntax error is caused by
using a bare name ('N') as a variable reference in the expression.
In order to avoid the syntax error, we spell the variable reference
as '$N' rather than simply 'N'.

The current command line parser is overly lax in places and allows a
branch whose name begins with a hyphen e.g. "-foo" to be created, but the
parseopt infrastructure in general does not like to parse anything that
begins with a dash as a short-hand refname. "git checkout -foo" won't
work, nor will "git branch -d -foo" (even though "git branch -d -- -foo"
works, it does so by mistake; we should not be taking anything but
pathspecs after double-dash).
All the codepaths that create a new branch ref, including the destination
of "branch -m src dst", use strbuf_check_branch_ref() to validate if the
given name is suitable as a branch name. Tighten it to disallow a branch
that begins with a hyphen.
You can still get rid of historical mistakes with
$ git update-ref -d refs/heads/-foo
and third-party Porcelains are free to keep using update-ref to create
refs with a path component that begins with "-".
