Neither %s nor %z are officially supported by python, they may work on
some (most?) platforms, but not all.

removed strftime use of %s and %z, which are not officially supported by python, with standard formats

rename READ_SHA1_FILE_REPLACE flag to LOOKUP_REPLACE_OBJECT

The READ_SHA1_FILE_REPLACE flag is more related to using the
lookup_replace_object() function rather than the
read_sha1_file() function.

We also need such a flag to be used with sha1_object_info()
instead of read_sha1_file().

The name LOOKUP_REPLACE_OBJECT is therefore better for this
flag.

replace_object: don't check read_replace_refs twice

Since e1111cef (inline lookup_replace_object() calls,
May 15 2011) the read_replace_refs global variable is
checked twice, once in lookup_replace_object() and
once again in do_lookup_replace_object().

As do_lookup_replace_object() is called only from
lookup_replace_object(), we can remove the check in
do_lookup_replace_object().

t6050: show that git cat-file --batch fails with replace objects

When --batch is passed to git cat-file, the sha1_object_info_extended()
function is used to get information about the objects passed to
git cat-file.

Unfortunately sha1_object_info_extended() doesn't take care of
object replacement properly, so it will often fail with a
message like this:

$ echo a3fb2e1845a1aaf129b7975048973414dc172173 | git cat-file --batch
a3fb2e1845a1aaf129b7975048973414dc172173 commit 231
fatal: object a3fb2e1845a1aaf129b7975048973414dc172173 change size!?

The goal of this patch is to show this breakage.

sha1_file: perform object replacement in sha1_object_info_extended()

sha1_object_info_extended() should perform object replacement
if it is needed.

The simplest way to do that is to make it call
lookup_replace_object_extended().

And now its "unsigned flags" parameter is used as it is passed
to lookup_replace_object_extended().

builtin/replace: teach listing using short, medium or full formats

By default when listing replace refs, only the sha1 of the
replaced objects are shown.

In many cases, it is much nicer to be able to list all the
sha1 of the replaced objects along with the sha1 of the
replacment objects.

And in other cases it might be interesting to also show the
types of the replaced and replacement objects.

This patch introduce a new --format=<fmt> option where
<fmt> can be any of the following:

	'short': this is the same as when no --format
		option is used, that is only the sha1 of
		the replaced objects are shown
	'medium': this also lists the sha1 of the
		replacement objects
	'full': this shows the sha1 and the type of both
		the replaced and the replacement objects

Some documentation and some tests will follow.

t6050: add tests for listing with --format

This patch adds tests for "git replace -l --format=<fmt>".

'short', 'medium' and 'full' are the only allowed values
for <fmt>.

'short' is the same as with no --format option.
Tests for 'medium' and 'full' are the most needed.

builtin/replace: unset read_replace_refs

When checking to see if some objects are of the same type
and when displaying the type of objects, git replace uses
the sha1_object_info() function.

Unfortunately this function by default respects replace
refs, so instead of the type of a replaced object, it
gives the type of the replacement object which might
be different.

To fix this bug, and because git replace should work at a
level before replacement takes place, let's unset the
read_replace_refs global variable at the beginning of
cmd_replace().

Drop unnecessary #includes from test-hashmap

Per Documentation/CodingGuidelines most C files in git start with
a #include of git-compat-util.h or another header file that includes
it, such as cache.h or builtin.h.  This file doesn't need anything
beyond "git-compat-util.h", so use that.

Remove a #include of the system header <stdio.h> since it is already
included by "git-compat-util.h".

pack-objects doc: treat output filename as opaque

After 1190a1a (pack-objects: name pack files after trailer hash,
2013-12-05), the SHA-1 used to determine the filename is calculated
differently.  Update the documentation to not guarantee anything more
than that the SHA-1 depends on the pack content somehow.

Hopefully this will discourage readers from depending on the old or
the new calculation.
