git-gui: Handle failure of core.worktree to identify the working directory.

Commit 21985a11 'git-gui: handle non-standard worktree locations' attempts
to use either GIT_WORK_TREE or core.worktree to set the _gitworktree
variable but these may not be set which leads to a failure to launch
gitk to review history. Use _gitdir to set the location for a standard
git layout where the parent of the .git directory is the working tree.

git-gui: fix "Explore Working Copy" for Windows again

It has already been fixed in commit 454efb47 (git-gui (Win): make
"Explore Working Copy" more robust, 2009-04-01), but has been broken in
commit 21985a11 (git-gui: handle non-standard worktree locations,
2010-01-23) by accidentally replacing too much with a new variable.

The problem can be reproduced when starting git-gui from within a
subdirectory. The solution is to convert the path name, explorer.exe is
invoked with, to a platform native name.

git-gui: fix PATH environment for mingw development environment

When creating a desktop shortcut from the gui the shortcut directly
starts wish with the git-gui script. In the msysgit development
environment some dll's reside in the mingw/bin directory which causes
that git can not start because libiconv2.dll is not found.

When using such a link the error is even more cryptic stating:
"child killed: unknown signal"

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.

git-gui: handle textconv filter on Windows and in development

When developing/testing we run git-gui.sh directly and the makefile

accessor to handle this case.

On Windows we may not find the shell so in this case revert to simply
executing the filter command without the shell intermediate.

On Windows, avoid git-gui to call Cygwin's nice utility

It's a common case for Windows developers to have both Cygwin and msysGit
installed. Unfortunately, some scenarios also require to have Cygwin in PATH.
By default, Cygwin comes with nice.exe, while msysGit does not. Since git-gui
calls nice if it is in PATH, this results in Cygwin's nice.exe being called
from msysGit's git-gui. Mixing Cygwin and msysGit generally is not a good idea,
and in this particular case it causes differences not being correctly detected.
So we only call nice.exe on Windows if it is in the same directory as git.exe.
This way, this work-around does neither affect a pure Cygwin environment, or
the case when nice.exe will be shipped with msysGit at some point in time.

This fixes msysGit issue 394.
