Allow using `git gui` command via MSYS2's MINGW32/64 subsystems (apropriate shells).
Just install apropriate `tk` package:
```bash
user@host MINGW32 ~
pacman -S mingw-w64-i686-tk
```
or
```bash
user@host MINGW64 ~
pacman -S mingw-w64-x86_64-tk
```

Hi Konstantin,
Thanks for the patch, and sorry for the late reply.

I think this should be the commit subject, instead of "msys2
compatibility patches".

Please don't just link to an external website. Put the explanation there
in the commit message. Explain what the problem was, and how this patch
fixes it.

This would convert the Windows style path to a Unix style path if we are
running in Cygwin, right? This is what I assume the heart of the problem
is.
Style nitpick: something like this would probably be better:
set oguilib {@@GITGUI_LIBDIR@@}
if {[is_Cygwin]} {
...
}
This makes it clear that Cygwin is the exception. For all other cases,
we want to use @@GITGUI_LIBDIR@@ directly.

I'm afraid I don't understand this hunk. I don't use Windows, and don't
completely understand the difference between cygwin, msys, etc. Could
you please explain further why this check is removed? Are there any
negative side-effects?

Why move the function? Can't this and the _iscygwin initialization just
stay in their place? It will make the diff much easier to read.

The startup script everywhere operates on Unix paths, but on Windows they are incomplete, and the interpreter expects full native paths.

It is true exactly the opposite.

To use `git gui` we need `tk` (wish), but `tk` (wish) can be available only when MSYSTEM is equal to MINGW32 or MINGW64.

Ok. Though I wonder if we need this variable at all. It is only used
with the function is_Cygwin, and seems like a performance optimization
so we don't need to perform the check for every call to the function.
But since it only is a couple of if statements, I'm not sure if it will
make a significant performance difference.

So if MYSYTEM is something other than these two, would it be possible to
run git-gui at all?

You should send another version of this series with the suggestions
implemented. Since you are using GitGitGadget, you can amend the commit,
force push it, and then issue another `/submit` command, and GGG will
take care of the rest. The GGG welcome message would have all the
details as well.
