`SamplePSReadLineProfile.ps1` SmartInsertQuote Error On Strict Mode

Inizia da PSReadLine/SamplePSReadLineProfile.ps1, alla condizione SmartInsertQuote collegata, ed esegui il profilo di esempio con Set-StrictMode -Version Latest. Riproduci l’errore spostandoti alla fine di una riga e inserendo una virgoletta, quindi verifica che la guardia gestisca quella posizione, inserisca due virgolette ed eviti l’eccezione index-out-of-range.

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version

Workaround

I edited the below line
https://github.com/PowerShell/PSReadLine/blob/caa53f8469e35f6ba6e1a434d4fc8efae2dde20c/PSReadLine/SamplePSReadLineProfile.ps1#L195
to add $cursor -lt $line.Length -and to beginning of the if block to short circuit and prevent the index out of range. I wasn't sure if $cursor - 1 inside the indexer would be appropriate as I don't completely understand all the code.
