error, when listing tags.

bfc04bb9b8 Correct usages of sed in git-tag for Mac OS X
Both `git-tag -l` and `git tag -v` fail on Mac OS X due to their
non-standard uses of sed.  Actually `git tag -v` fails because the
underlying git-tag-verify uses a non-standard sed command.

We now stick to only standard sed, which does make our sed scripts
slightly more complicated, but we can actually list tags with more
than 0 lines of additional context and we can verify signed tags
with gpg.  These major Git functions are much more important than
saving two or three lines of a simple sed script.

7051c3b129 git-cvsimport: force checkout of working tree after initial import
When creating a brand new git repository through git-cvsimport (not
incremental import), force a checkout of HEAD of master as working tree
after successful import using the -f switch to git checkout.  Otherwise
the working tree is empty, and all files are reported as 'deleted' by
git status.

ef5a6fb597 Add test-script for git-tag
These tests are useful to develop the C version for git-tag.sh,
ensuring that the future builtin-tag.c will not break previous
behaviour.

The tests are focused on listing, verifying, deleting and creating
tags, checking always that the correct status value is returned
and everything remains as expected.

In order to verify and create signed tags, a PGP key was also
added, being created this way: gpg --homedir t/t7004 --gen-key
Type DSA and Elgamal, size 2048 bits, no expiration date.

5483c71d7a git-send-email: make options easier to configure.
This change makes git-send-email's behavior easier to modify by adding config
equivalents for two more of git-send-email's flags.

The mapping of flag to config setting is:
  --[no-]supress-from => sendemail.suppressfrom
  --[no-]signed-off-cc => sendemail.signedoffcc

It renames the --threaded option to --thread/--no-thread; the

30d038e2ff Add test script for git-stripspace.
These tests check some features that git-stripspace already has
and those that it should manage well: Removing trailing spaces
from lines, removing blank lines at the beginning and end,
unifying multiple lines between paragraphs, doing the correct
when there is no newline at the last line, etc.

It seems that the implementation needs to save the whole line
in memory to be able to manage correctly long lines with
text and spaces conveniently distribuited on them.

9690c118fa Fix git-stripspace to process correctly long lines and spaces.
Now the implementation gets more memory to store completely
each line before removing trailing spaces, and does it right
when the last line of the file ends with spaces and no newline
at the end.

Function stripspace needs again to be non-static in order to call
it from "builtin-tag.c" and the upcoming "builtin-commit.c".
A new parameter skip_comments was also added to the stripspace
function to optionally strips every shell #comment from the input,
needed for doing this task on those programs.

7e508eb1a2 git-gui: Don't require a .pvcsrc to create Tools/Migrate menu hack
The Tools/Migrate menu option is a hack just for me.  Yes, that's
right, git-gui has a hidden feature that really only works for me,
and the users that I support within my day-job's great firewall.
The menu option is not supported outside of that environment.

In the past we only enabled Tools/Migrate if our special local
script 'gui-miga' existed in the proper location, and if there
was a special '.pvcsrc' in the top level of the working directory.
This latter test for the '.pvcsrc' file is now failing, as the file
was removed from all Git repositories due to changes made to other
tooling within the great firewall's realm.

I have changed the test to only work on Cygwin, and only if the
special 'gui-miga' is present.  This works around the configuration
changes made recently within the great firewall's realm, but really
this entire Tools/Migrate thing should be abstracted out into some
sort of plugin system so other users can extend git-gui as they need.

f09c9b8c5f Teach rebase -i about --preserve-merges
The option "-p" (or long "--preserve-merges") makes it possible to
rebase side branches including merges, without straightening the
history.

Example:

           X
            \
         A---M---B
        /
---o---O---P---Q

When the current HEAD is "B", "git rebase -i -p --onto Q O" will yield

               X
                 \
---o---O---P---Q---A'---M'---B'

Note that this will

- _not_ touch X [*1*], it does

- _not_ work without the --interactive flag [*2*], it does

- _not_ guess the type of the merge, but blindly uses recursive or
  whatever strategy you provided with "-s <strategy>" for all merges it
  has to redo, and it does

- _not_ make use of the original merge commit via git-rerere.

*1*: only commits which reach a merge base between <upstream> and HEAD
     are reapplied. The others are kept as-are.

*2*: git-rebase without --interactive is inherently patch based (at
     least at the moment), and therefore merges cannot be preserved.

1164f1e48d Fix zero-object version-2 packs
A pack-file can get created without any objects in it (to transfer "no

or just otherwise just end up transferring only branch head information
and already have all the objects themselves).

And while we probably should never create an index for such a pack, if we
do (and we do), the index file size sanity checking was incorrect.

706d6c3e76 gitk: Add a progress bar to show progress while resetting
Since git reset now gets chatty while resetting, we were getting errors
reported when a reset was done using the "reset branch to here" menu
item.  With this we now read the progress messages from git reset and
update a progress bar.  Because git reset outputs the progress messages
to standard error, and Tcl treats messages to standard error as error
messages, we have to invoke git reset via a shell and redirect standard
error into standard output.

This also fixes a bug in computing descendent heads when head ids
are changed via a reset.

1b1dce4bae Teach rebase an interactive mode
Don't you just hate the fact sometimes, that git-rebase just applies
the patches, without any possibility to edit them, or rearrange them?
With "--interactive", git-rebase now lets you edit the list of patches,
so that you can reorder, edit and delete patches.

Such a list will typically look like this:

	pick deadbee The oneline of this commit
	pick fa1afe1 The oneline of the next commit
	...

By replacing the command "pick" with the command "edit", you can amend
that patch and/or its commit message, and by replacing it with "squash"
you can tell rebase to fold that patch into the patch before that.

It is derived from the script sent to the list in

161fea832a Teach bash how to complete +refspec on git-push
Using `git push origin +foo` to forcefully overwrite the remote
branch named foo is a common idiom, especially since + is shorter
than the long option --force and can be specified on a per-branch
basis.

We now complete `git push origin +foo` just like we do the standard
`git push origin foo`.  The leading + on a branch refspec does not
alter the completion.

9378c16135 Add core.quotepath configuration variable.
We always quote "unusual" byte values in a pathname using
C-string style, to make it safer for parsing scripts that do not
handle NUL separated records well (or just too lazy to bother).
The absolute minimum bytes that need to be quoted for this
purpose are TAB, LF (and other control characters), double quote
and backslash.

However, we have also always quoted the bytes in high 8-bit
range; this was partly because we were lazy and partly because
we were being cautious.

This introduces an internal "quote_path_fully" variable, and
core.quotepath configuration variable to control it.  When set
to false, it does not quote bytes in high 8-bit range anymore
but passes them intact.

The variable defaults to "true" to retain the traditional
behaviour for now.

aeb5932845 git-send-email: Do not make @-less message ID
When the original $from address fails to yield a valid-looking
e-mail address, we created a bogus looking message ID, formatted
like this:

	Message-Id: <11823357623688-git-send-email->

This commit fixes it by moving call to make_message_id() to
where it matters, namely, before the $message_id is needed to be
placed in the generated e-mail header; this has an important
side effect of making it clear that $from is already available.

Also throw in Sys::Hostname::hostname() just for fun, although I
suspect that the code would never trigger due to the modified
call sequence that makes sure $from is always available.  This
is based on a suggestion by Michael Hendricks.
