git-gui: Make commit log messages end with a newline
Concatenating commit log messages from multiple commits works better

the correct size of the main window whenever the layout changes,

We explicitly resolve all paths in the objects/info/alternates as

access the exact same locaton as the source repository, even if
relative paths had been used before.

git-gui: Allow users to choose/create/clone a repository
If we are started outside of a git repository than it is likely
the user started us from some sort of desktop shortcut icon in
the operating system. In such a case the user is expecting us to
prompt them to locate the git repository they want to work on,
or to help them make a new repository, or to clone one from an
existing location. This is a very simple wizard that offers the
user one of these three choices.
When we clone a repository we always use the name `master` in the
local repository, even if the remote side does not appear to point
to that name. I chose this as a policy decision. Much of the Git
documentation talks about `master` being the default branch in a
repository and that's what git-init does too. If the remote side
doesn't call its default branch `master` most users just don't care,
they just want to use Git the way the documentation describes.
Rather than relying on the git-clone Porcelain that ships with
git we build the new repository ourselves and then obtain content
by git-fetch. This technique simplifies the entire clone process
to roughly: `git init && git fetch && git pull`. Today we use
three passes with git-fetch; the first pass gets us the bulk of
the objects and the branches, the second pass gets us the tags,
and the final pass gets us the current value of HEAD to initialize
the default branch.
If the source repository is on the local disk we try to use a
hardlink to connect the objects into the new clone as this can
be many times faster than copying the objects or packing them and
passing the data through a pipe to index-pack. Unlike git-clone
we stick to pure Tcl [file link -hard] operation thus avoiding the
need to fork a cpio process to setup the hardlinks. If hardlinks
do not appear to be supported (e.g. filesystem doesn't allow them or
we are crossing filesystem boundaries) we use file copying instead.

we cannot function correctly. Because we need that to get the
version so we can load our library correctly we cannot rely on
the library function "error_popup" here, as this is all running
before the library path has been configured, so error_popup is
not available to us.

Cygwin has been stuck on the 8.4.1 version of Tcl/Tk for quite some
time, even though the main Tcl/Tk distribution is already shipping
an 8.4.15. The problem is Tcl/Tk no longer supports Cygwin so
apparently building the package for Cygwin is now a non-trivial task.
Its actually quite easy to build the native Win32 version of Tcl/Tk
by compiling with the -mno-cygwin flag passed to GCC but this means
we lose all of the "fancy" Cygwin path translations that the Tcl
library was doing for us. This is particularly an issue when we
are trying to start git-gui through the git wrapper as the git
wrapper is passing off a Cygwin path for $0 and Tcl cannot find
the startup script or the library directory.
We now use `cygpath -m -a` to convert the UNIX style paths to Windows
style paths in our startup script if we are building on Cygwin.
Doing so allows either the Cygwin-ized Tcl/Tk 8.4.1 that comes with
Cygwin or a manually built 8.4.15 that is running the pure Win32
implementation to read our script.

git-gui: Disable native platform text selection in "lists"
Sometimes we use a Tk text widget as though it were a listbox.
This happens typically when we want to show an icon to the left
of the text label or just when a text widget is generally a better
choice then the native listbox widget.
In these cases if we want the user to have control over the selection
we implement our own "in_sel" tag that shows the selected region
and we perform our own selection management in the background
via keybindings and mouse bindings. In such uses we don't want
the user to be able to activate the native platform selection by
dragging their mouse through the text widget. Doing so creates a
very confusing display and the user is left wondering what it may
mean to have two different types of selection in the same widget.
Tk doesn't allow us to delete the "sel" tag that it uses internally
to manage the native selection but it will allow us to make it
invisible by setting the tag to have the same display properties
as unselected text. So long as we don't actually use the "sel"
tag for anything in code its effectively invisible.

The Tcl expression "[append [mc Foo] Bar]" does not return the string
"FooBar" after translation; instead it is setting the variable Foo to
the value Bar, or if Foo is already defined it is appending Bar onto
the end of it. This is *not* what we wanted to have happen here.
Tcl's join function is actually the correct function but its default
joinStr argument is a single space. Unfortunately all of our call
sites do not want an extra space added to their string. So we need
a small wrapper function to make the call to join with an empty
join string. In C this is (roughly) the job of the strcat function.
Since strcat is not yet used at the global level it is a reasonable
name to use here.
