magit-locate-emacsclient: quote value

Also remove an unused variable.
AUTHORS.md: update list of contributors
magit-insert-stashes: work around issue in Git <1.7.10.3

Closes issue #1427.
magit-ediff: correct doc-string

The range is passed directly to `git diff' which, when given
a single commit, compares the working tree with that commit.
magit-commit-add-log: properly abort if nothing is committed

See #1438.
magit-push-tags: respect popup arguments
magit-rev-parse: accept any numbers of arguments

On the next branch this was done several months ago.  The callers where
then adjusted to take advantage of the new flexibility.  Here we only
change this function itself.  We do so to make the Org-Magit package
compatible with Magit's master branch again, see magit/org-magit#1.
magit-locate-emacsclient: deal with invocation-directory being nil

See #1443.
bind j instead of M-g to magit-jump-to-diffstats

Do so in the two relevant keymaps `magit-commit-mode-map' and
`magit-diff-mode-map'.  In other maps `j' is bound to the related
`magit-section-jump-map'.
magit.el: explicitly set coding system to utf-8

Unlike the other libraries `magit.el' contains some non-ascii
characters.  Usually Emacs used utf-8 if nothing else is specified
but for some language environments this does not seem to be the case.
magit-mode-refresh-buffer: don't fiddle with window point

See #1451.
magit-locate-emacsclient: kludge for multi-arch Emacs for Mac OS X
magit-commit-add-log: Use symbol boundary in function name REGEXP

Use symbol boundary instead of word boundary in function name REGEXP. This is
because using word boundary causes partial function name being matched. As an
example, let's say we have two diff hunks, one in the function `foo' and the
other in `foo-bar'. When the word boundary REGEXP is used, the REGEXP matches
both function name `foo' and `foo-bar', which will prevent
`magit-commit-add-log' from adding a log entry for function `foo-bar' if an
entry for function `foo' already exist.
Add a defcustom for `magit-status-mode-hook'.

This will allow users to customize it and extension packages, such as
magit-filenotify, to use `custom-add-option' to add themselves as option
to it.
Add `magit-load-config-extensions' option to `magit-mode-hook'.

This will make it easier and more noticeable when customizing magit.
Add options for stgit, svn, topgit to `magit-mode-hook'.

This will make them more noticeable when customizing magit and easier to
enable.

magit-commit-add-log: Use symbol boundary in function name REGEXP
Merge pull request #1456 from ruediger/customhookoptions

Provide options for `magit-mode-hook`
magit-list-repos*: skip inaccessible directories

Fixes #1463.
avoid needlessly connecting to unrelated tramp remotes

In `magit-save-buffers-predicate-tree-only' avoid needlessly connecting
to unrelated tramp remotes by first checking whether the absolute path
to the top-level of the current directory is a prefix of
`buffer-file-name'.  Only if that is so check whether `buffer-file-name'
is actually directly in that repository (it may also be part of a
submodule or other nested repository.

Fixes #1473.
