Line continuation with line-initial | (pipe symbol) not recognized on Unix-like platforms. #1261
Description
PS Core now supports continuing a pipeline by placing the | at the start of the following line.
On Windows pasting such a pipeline works fine, but not on Unix-like platforms (macOS, Linux).
Environment data
PS version: 7.0.0-rc.1
PSReadline version: 2.0.0-rc1
os: Darwin MkiMac.home 19.0.0 Darwin Kernel Version 19.0.0: Thu Oct 17 16:17:15 PDT 2019; root:xnu-6153.41.3~29/RELEASE_X86_64 x86_64
PS file version: 7.0.0.0
HostName: ConsoleHost
BufferWidth: 180
BufferHeight: 60
Steps to reproduce or exception report
On macOS or Linux, paste the following in a PowerShell terminal:
Get-Date
| % ToUniversalTime
This works fine on Windows, but on Unix-like platforms the 2nd line is unexpectedly treated as a new command, which predictably fails:
ParserError:
Line |
1 | | % ToUniversalTime
| ^ An empty pipe element is not allowed.

Sorry, Jason Shirk (@lzybkr), I accidentally submitted this without content first - the report is now complete.

This is, actually related to certain terminals, and so can be reproduced on Windows as well if not using ConsoleHost (VS Code's terminal is a prime suspect), and it has to do with whether the paste operation is performed by the terminal, or handled directly by PSReadLine.
I think Jason Shirk (@lzybkr) or Dongbo Wang (@daxian-dbw) might be looking in to a solution, related to the speed at which input characters are arriving for processing, and using that as a signal that the terminal is 'pasting'.
This is then, effectively, a duplicate to #579. Pasting on 'nix is equivalent to right-click pasting on Windows.

Thanks, Carl Morris (@msftrncs) - I keep forgetting about #579; indeed sounds like I've created another duplicate, so I'm closing this.
