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.

* Demonstrates a conhost hang that occurs when widening the console buffer
|
|
* while selection is in progress. The problem affects the new Windows 10
|
|
* console, not the "legacy" console mode that Windows 10 also includes.
|
|
*
|
|
* First tested with:
|
|
* - Windows 10.0.10240
|
|
* - conhost.exe version 10.0.10240.16384
|
|
* - ConhostV1.dll version 10.0.10240.16384
|
|
* - ConhostV2.dll version 10.0.10240.16391
