git-gui: Avoid using the <<Copy>> binding as a menu accelerator on win32
On Windows the Control-C binding is used to copy and is mapped to the Tk
virtual event <<Copy>>. In the initial git-gui dialog this is also bound
as an accelerator for the Clone menu item. The effect is that both bindings
run, copying the text but resetting the clone page or switching to the clone
page when the user tries to copy text from one of the entry fields.
This patch avoids this by using Control-L instead for Windows only.

When performing a non-interactive rebase, sometimes
"git rebase --continue" will fail if an unmodified file is

You must edit all merge conflicts and then

This is caused by "git diff-files" reporting a difference

upload-pack: remove unused "create_full_pack" code in do_rev_list
A bit of history in chronological order, the newest at bottom:
- 80ccaa7 (upload-pack: Move the revision walker into a separate function.)
do_rev_list was introduced with create_full_pack argument
- 21edd3f (upload-pack: Run rev-list in an asynchronous function.)
do_rev_list was now called by start_async, create_full_pack was
passed by rev_list.data
- f0cea83 (Shift object enumeration out of upload-pack)
rev_list.data was now zero permanently. Creating full pack was
done by passing --all to pack-objects
- ae6a560 (run-command: support custom fd-set in async)
rev_list.data = 0 was found out redudant and got rid of.
Get rid of the code as well, for less headache while reading do_rev_list.

git-rebase--interactive.sh: use printf instead of echo to print commit message
On systems with an echo which defaults to the XSI-conformant behavior
(Solaris, or others using Ksh), echo will interpret certain backslashed
characters as control sequences. This can cause a problem for interactive
rebase when it is used to rebase commits whose commit "subject" (the first
line) contains any of these backslashed sequences. In this case, echo will
substitute the control sequence for the backslashed characters and either
the rebased commit message will differ from the original, or the rebase
process will fail. Neither is desirable.
So work around this issue by replacing the echo statements used to print
out portions of the commit message, with printf.
Also, add a test to test for this breakage.

rebase: protect against diff.renames configuration
We currently do not disable diff.renames configuration while rebase
internally runs "format-patch" to feed "am -3".
The end user configuration for "diff" should not affect the result
produced by the higher level command that is related to "diff" only
because internally it is implemented in terms of it.
For that matter, I have a feeling that format-patch should not even look
at diff.renames, but we seem to have been doing this for a long time so
there is no easy way to fix this thinko.
In any case, here is a much straightforward fix for "rebase".

Teach "apply --index-info" to handle rename patches
With v1.5.3.2~14 (apply --index-info: fall back to current index for

about the lack of diff index line when a file already present in the
current index had no content change.
But it still worries too much: for rename patches, it is checking
that both the old and new filename are present in the current
index. This makes no sense, since a file rename generally
involves creating a file there was none before.
So just check the old filename.

git itself to get them using the revision IDs present in the message already.
