git-completion.bash: lexical sorting for diff.statGraphWidth

df44483a (diff --stat: add config option to limit graph width,
2012-03-01) added the option diff.startGraphWidth to the list of
configuration variables in git-completion.bash, but failed to notice
that the list is sorted alphabetically.  Move it to its rightful place
in the list.

git-completion.bash: add diff.submodule to config list

c47ef57 (diff: introduce diff.submodule configuration variable,
2012-11-13) introduced the diff.submodule configuration variable, but
forgot to teach git-completion.bash about it.  Fix this.

git-completion.bash: complete branch.*.rebase as boolean

6fac1b83 (completion: add missing config variables, 2009-06-29) added
"rebase" to the list of completions for "branch.*.*", but forgot to
specify completions for the values that this configuration variable
can take (namely "false" and "true").  Fix this.

complete: zsh: trivial simplification

There should be no functional changes.

The only reason I wrapped this code around a sub-function is because zsh
did the same in it's bashcompinit script in order to declare the special
variable 'words' as hidden, but only in this context.

There's no need for that any more since we access __git_main directly,
so 'words' is not modified, so there's no need for the sub-function.

In zsh mode the array indexes are different though.

complete: zsh: use zsh completion for the main cmd

So that we can have a nice zsh completion output:

% git <tab>
add       -- add file contents to the index
bisect    -- find by binary search the change that introduced a bug
branch    -- list, create, or delete branches
checkout  -- checkout a branch or paths to the working tree
clone     -- clone a repository into a new directory
commit    -- record changes to the repository
diff      -- show changes between commits, commit and working tree, etc
fetch     -- download objects and refs from another repository
grep      -- print lines matching a pattern
init      -- create an empty Git repository or reinitialize an existing one
log       -- show commit logs
merge     -- join two or more development histories together
mv        -- move or rename a file, a directory, or a symlink
pull      -- fetch from and merge with another repository or a local branch
push      -- update remote refs along with associated objects
rebase    -- forward-port local commits to the updated upstream head
reset     -- reset current HEAD to the specified state
rm        -- remove files from the working tree and from the index
show      -- show various types of objects
status    -- show the working tree status
tag       -- create, list, delete or verify a tag object signed with GPG

And other niceties, like 'git --git-dir=<tab>' showing only directories.

For the rest, the bash completion stuff is still used.

Also, add my copyright, since this more than a thin wrapper.

git-svn: test fix occasional "Failed to strip path" error on fetch next commit, try #2
git-svn: fix occasional "Failed to strip path" error on fetch next commit, try #2

When --stdlayout and --preserve-empty-dirs flags are used and a
directory becomes empty, two things happen:

Sometimes find_empty_directories() returns empty list and no empty dir
placeholder file created. This happens, because find_empty_directories()
marks all directories as non-empty, if at least one updated directory is
non-empty.

Sometimes git-svn dies with "Failed to strip path" error. This happens,
because find_empty_directories() returns git paths and
add_placeholder_file() expects svn paths
git-svn-test: don't test for possible bug "Failed to strip path", try #2

In the previous commit a showcase was added to
t9160-git-svn-preserve-empty-dirs.sh for the "Failed to strip path" bug.
Now the flag --stdlayout should be enough.
git-svn: test fetch erroneously recreating empty dir placeholder deleted earlier, try #2
git-svn: fix svn fetch erroneously recreating empty dir placeholder deleted earlier, try #2

The Fetcher accumulates deleted paths in an array and doesn't reset the
array on next commit. This causes different results when interrupting
and resuming the fetch.
When --preserve-empty-dirs flag is used, a path in the array can be
erroneously treated as just deleted (although it was deleted in the
previous commit) and cause the creation of an empty dir placeholder.
