Makefile: explicitly set target name for autogenerated dependencies

"gcc -MF depfile -MMD -MP -c -o path/to/file.o" produces a makefile
snippet named "depfile" describing what files are needed to build the
target given by "-o".  When ccache versions before v3.0pre0~187 (Fix
handling of the -MD and -MDD options, 2009-11-01) run, they execute

gcc -MF depfile -MMD -MP -E

instead to get the final content for hashing.  Notice that the "-c -o"
combination is replaced by "-E".  The result is a target name without
a leading path.

Thus when building git with such versions of ccache with
COMPUTE_HEADER_DEPENDENCIES enabled, the generated makefile snippets
define dependencies for the wrong target:

$ make builtin/add.o
GIT_VERSION = 1.7.8.rc3
    * new build flags or prefix
    CC builtin/add.o
$ head -1 builtin/.depend/add.o.d
add.o: builtin/add.c cache.h git-compat-util.h compat/bswap.h strbuf.h \

After a change in a header file, object files in a subdirectory are
not automatically rebuilt by "make":

$ touch cache.h
$ make builtin/add.o
$

Luckily we can prevent trouble by explicitly supplying the name of the
target to ccache and gcc, using the -MQ option.  Do so.

branch: let branch filters imply --list

Currently, a branch filter like `--contains`, `--merged`, or
`--no-merged` is ignored when we are not in listing mode.
For example:

  git branch --contains=foo bar

will create the branch "bar" from the current HEAD, ignoring
the `--contains` argument entirely. This is not very
helpful. There are two reasonable behaviors for git here:

  1. Flag an error; the arguments do not make sense.

  2. Implicitly go into `--list` mode

This patch chooses the latter, as it is more convenient, and
there should not be any ambiguity with attempting to create
a branch; using `--contains` and not wanting to list is
nonsensical.

That leaves the case where an explicit modification option
like `-d` is given.  We already catch the case where
`--list` is given alongside `-d` and flag an error. With
this patch, we will also catch the use of `--contains` and
other filter options alongside `-d`.

CodingGuidelines: add Python coding guidelines

These are kept short by simply deferring to PEP-8.  Most of the Python
code in Git is already very close to this style (some things in contrib/
are not).

Rationale for version suggestions:

 - Amongst the noise in [1], there isn't any disagreement about using
   2.6 as a base (see also [2]), although Brandon Casey recently added
   support for 2.4 and 2.5 to git-p4 [3].

 - Restricting ourselves to 2.6+ makes aiming for Python 3 compatibility
   significantly easier [4].

 - Advocating Python 3 support in all scripts is currently unrealistic
   because:

     - 'p4 -G' provides output in a format that is very hard to use with
       Python 3 (and its documentation claims Python 3 is unsupported).

     - Mercurial does not support Python 3.

     - Bazaar does not support Python 3.

 - But we should try to make new scripts compatible with Python 3
   because all new Python development is happening on version 3 and the
   Python community will eventually stop supporting Python 2 [5].

 - Python 3.1 is required to support the 'surrogateescape' error handler
   for encoding/decodng filenames to/from Unicode strings and Python 3.0
   is not longer supported.

add: warn when -u or -A is used without pathspec

Most Git commands that can be used with or without pathspec operate
tree-wide by default, the pathspec being used to restrict their
scope.  A few exceptions are: 'git grep', 'git clean', 'git add -u'
and 'git add -A'.  When run in a subdirectory without pathspec, they
operate only on paths in the current directory.

The inconsistency of 'git add -u' and 'git add -A' is particularly
problematic since other 'git add' subcommands (namely 'git add -p'
and 'git add -e') are tree-wide by default.  It also means that "git
add -u && git commit" will record a state that is different from
what is recorded with "git commit -a".

Flipping the default now is unacceptable, so let's start training
users to type 'git add -u|-A :/' or 'git add -u|-A .' explicitly, to
prepare for the next steps:

* forbid 'git add -u|-A' without pathspec (like 'git add' without
  option)

* much later, maybe, re-allow 'git add -u|-A' without pathspec, that
  will add all tracked and modified files, or all files, tree-wide.

A nice side effect of this patch is that it makes the :/ magic
pathspec easier to discover for users.

When the command is called from the root of the tree, there is no
ambiguity and no need to change the behavior, hence no need to warn.

git-remote-testpy: fix path hashing on Python 3

When this change was originally made (0846b0c - git-remote-testpy:
hash bytes explicitly , I didn't realise that the "hex" encoding we
chose is a "bytes to bytes" encoding so it just fails with an error
on Python 3 in the same way as the original code.

It is not possible to provide a single code path that works on
Python 2 and Python 3 since Python 2.x will attempt to decode the
string before encoding it, which fails for strings that are not
valid in the default encoding.  Python 3.1 introduced the
"surrogateescape" error handler which handles this correctly and
permits a bytes -> unicode -> bytes round-trip to be lossless.  As
the original came from reading the filesystem path, we convert them
back into the original bytes encoded in sys.getfilesystemencoding().

At this point Python 3.0 is unsupported so we don't go out of our
way to try to support it.
