Steps to reproduce
$line = 'gps | format-table -Property @{'
$exp = TabExpansion2 $line $line.Length
$exp.ReplacementIndex
$exp.ReplacementLength
$exp.CompletionMatches.CountExpected behavior
ReplacementIndex should be $line.Length, the length should be 0.
If you change the repro to add a space at the end, then you will see 32, 0, 5
$line = 'gps | format-table -Property @{ 'Actual behavior
The replacement index and length are negative.
This raises an exception in PSReadLine (PowerShell/PSReadLine#534)
In Windows PowerShell, if you remove PSReadLine and try tab interactively (instead of manually calling TabExpansion2), PowerShell will crash - as in exit after reporting a crash to Watson.
PowerShell ISE doesn't crash, but it also doesn't complete anything.
