Especially for Windows users used to work with the Windows Explorer,
it is very useful when after picking a repository (either opening
a local one or initializing/cloning a new one) in the "intro" window,
the explorer view of the working copy pops up along the standard
Git GUI window, so that the users can, well, actually work with
the repository.

Especially when cloning is finished, the Git GUI window pops up,
but there is not really much one can do within it - there needs to be
a way to easily start exploring and working with the new working copy
using the standard system interface: explorer.exe on Windows, open on
MacOS/X and xdg-open as a fallback (all modern Linux desktops).

This might be also a post-clone option instead (possibly opening the window
automagically) but I believe that this might be useful also in other
situations, e.g. you don't have to keep the working copy window around
if you work in multiple repositories.

This operation will not make sense on bare repositories.

If a merge tool was invoked on a conflicted file and the tool completed,
then the conflicted file was staged automatically. However, the fact that
the user closed the merge tool cannot be understood as the unequivocal
sign that the conflict was completely resolved. For example, the user

have accidentally closed the tool. We better leave the file unstaged and

- Make diffs and blame default to the system (locale)
  encoding instead of hard-coding UTF-8.
- Add a gui.encoding option to allow overriding it.
- gitattributes still have the final word.

The rationale for this is Windows support:

1) Windows people are accustomed to using legacy encodings
   for text files. For many of them defaulting to utf-8
   will be counter-intuitive.
2) Windows doesn't support utf-8 locales, and switching
   the system encoding is a real pain. Thus the option.

This patch also adds proper encoding conversion to Apply Hunk/Line.

Most commits have author name encoded in UTF-8, but the incremental
blame output dumps raw bytes and doesn't give us the encoding header
from the commit.  Rather than fixing up tooltip data after we have
viewed that particular commit in the blame viewer we can assume all
names are in UTF-8.

This is still going to cause problems when the author name is not
encoded in UTF-8, but the only (efficient) way to solve that is to
add an "encoding" header to the blame --incremental mode output,
as otherwise we need to run `git cat-file commit $sha1` for each
and every commit identified and that would be horribly expensive
on any platform.
Signed-off-by: NShawn O. Pearce <spearce@spearce.org>

Most folks using git-gui on internationalized files have complained
that it doesn't recognize UTF-8 correctly.  In the past we have just
ignored the problem and showed the file contents as binary/US-ASCII,
which is wrong no matter how you look at it.

This really should be a per-file attribute, managed by .gitattributes,
so we now pull the "encoding" attribute data for the given path from
the .gitattributes (if available) and use that, falling back to UTF-8
if the attributes are unavailable, git-check-attr is broken, or an
encoding for this path not specified.

We apply the encoding anytime we show file content, which currently
is limited to only the diff viewer and the blame viewer.

  git-gui: Fix diff parsing for lines starting with "--" or "++"

Languages like Lua and SQL use "--" to mark a line as commented out.
If this appears at column 0 and is part of the pre-image we may see
"--- foo" in the diff, indicating that the line whose content is
 "-- foo" has been removed from the new version.

git-gui was incorrectly parsing "--- foo" as the old file name
in the file header, causing it to generate a bad patch file when
the user tried to stage or unstage a hunk or the selected line.
We need to keep track of where we are in the parsing so that we do
not misread a deletion or addition record as part of the header.

	REMOTE:
	[diff :1:$path :3:$path]

2) Conflict involving symlinks:
	LOCAL:
	[diff :1:$path :2:$path]
