When running on systems that do not support a virtual terminal,
the tests was incorrectly assuming escape sequences were removed.
The fix is to expect different results depending on whether or not
the host supports virtual terminal mode.
* Wire up proper ConsoleHostRawUserInterface.LengthInBufferCells for Unix
Ref https://github.com/PowerShell/PowerShell/issues/2502
This allows for Unix console host to properly calculate display width for
strings containing escape sequences (e.g. ANSI color), rather than
falling back to naive string.Length.
* Add basic tests for host LengthInBufferCells calculation
PowerShell can be started with input redirected in different scenarios.
`powershell -Command -` is one scenario where commands are sent to
PowerShell, but this is not a interactive shell scenario, it's really
a server to run commands from some other process.
`powershell -File -` or just regular redirected input means PowerShell
is an interactive shell, but command line editing must be done via
the redirected standard input handle instead of interacting directly
with a console handle.
In this scenario, we want to provide a good editing experience. Today,
we provide the bare minimum, supporting backspace but no cursor movement.
The bug here is that backspace was treated as a backspace in the server mode
but should not have been.
The input loop reading from stdin did not handle multi-line input correctly
because it was adding a newline character where none was expected.
The fix was to not include the final newline character to accept input,
just like Console.ReadLine or PSReadline would.
This restructuring moves tests to a directory name which matches the module
in which the cmdlet resides which should improve the discoverability of a
specific test.
For tests which are not about cmdlets in a module, new directories have been
created to make those tests easier to find as well
