- Double quotes escaping issue for default shell
- for common shells, like powershell, bash, cygwin, double quotes are added to the path of default shell and its arguments, and the double quotes and backslash inside args are escaped.
- For cmd and ssh-shellhost.exe, double quotes to shell and its arguments are added without any escaping.
- For shell other than above, a registry value DefaultShellEscapeArguments" under "HKEY_LOCAL_MACHINE\SOFTWARE\OpenSSH" is added (see [DefaultShell](https://github.com/PowerShell/Win32-OpenSSH/wiki/DefaultShell)). The default value when missing is 1, which mean the escaping will happen like no.1 above. If non-escaping is preferred, this value needs to be set to 0. in later case, only double quotes are added to shell and args, like no.2 above.
| DefaultShell | DefaultShellEscapeArguments |ShellPath is double quoted |" and \ are escaped in arguments|
|--|--|--|--|
| powershell | 1, 0, missing | yes | yes |
| bash | 1, 0, missing | Yes | Yes|
| cygwin | 1, 0, missing | Yes | Yes |
| cmd.exe | 1, 0, missing | Yes | No |
| ssh-shellhost.exe | 1, 0, missing | Yes | No |
| Other custom shells | 1, missing | Yes | Yes |
| Other custom shells | 0 | Yes | No|
Please refer to [DefaultShell](https://github.com/PowerShell/Win32-OpenSSH/wiki/DefaultShell) for setting DefaultShell and DefaultShellEscapeArguments.
