TODO in a test on argument separation in command parser

[ForNeVeR]

See the code near this line: https://github.com/ant-druha/intellij-powershell/blob/baccc65fb41e834e8eb66642911f1a1259926856/src/test/resources/testData/parser/PathExpression.ps1#L30

So, this is in a test that checks how the command arguments are parsed. We should check if the comment corresponds to the actual PowerShell implementation, and if our current parser also corresponds to this.
