My motivation at the moment is that I'm trying to share a
git checkout between multiple VMs using VirtualBox's Shared
Folders feature. git in the guest VM isn't able to see the
executable bits from the host due to the VirtualBox/SMB/CIFS
layer. Instead, it thinks text files are non-executable,
unless they have a shebang line. That's a sensible way to
set the flags anyway, so set them like that.
With this commit, there's still one file that isn't handled:
src/shared/GetCommitHash.cmd. It's still marked executable,
but it lacks a shebang line, so the guest thinks it's
non-executable. I'm not sure it should be changed.
There are three reasons for this change:
* It's consistent with MSYS2, which already renamed console.exe to
winpty.exe.
* winpty.exe is less likely to clash with another program.
* winpty.exe is easier to search for online. If someone unfamiliar with
winpty is asked to run console.exe, they might have a hard time figuring
out where console.exe comes from.
The old behavior can be restored by passing UNIX_ADAPTER_EXE=console.exe
to `make`, or by simply renaming the binary after-the-fact, or with
`alias`, etc.
* ^[O is Shift-Alt-O, not Alt-O. Alt-O is ^[o
* '[' is not a valid virtualkey. It's typically VK_OEM_4 on a US
keyboard, but it needs to be looked up dynamically.
* The unicodeChar fields should be 'O' and '[', not NUL.
* Add a --showkey argument to the unix adapter.
My Ubuntu machine has a nice showkey -a utility that dumps keys, but I
can't find something similar for Cygwin/MSYS. It's a very useful tool
for debugging UNIX terminal interoperability, so add it to the unix
adapter.
* Add WINPTY_DEBUG=input to log input bytes and console key events.
