[Bug] Unused argument not detected if part of string literal

[Rikerfi]

What happened?

Rule 0919 Keyword argument is not used (unused-argument) is not working right if an argument is part of a string literal.

What command/code did you try to run?

*** Settings ***
Documentation  Unused argument


*** Test Cases ***
Argument Test
    [Documentation]  TC
    Say Greetings  Hi  Peter


*** Keywords ***
Say Greetings
    [Documentation]  KW
    [Arguments]  ${greetings}  ${dude}
    Log  ${greetings} dude

I noticed that the following keyword is detected correctly.

Say Greetings All Unused
    [Documentation]  KW - This works fine.
    [Arguments]  ${greetings}  ${dude}
    Log  greetings dude

What is the full error message?

No rule 0919 violation detected.

What did you expect to happen instead?

[W] 0919 Keyword argument '${dude}' is not used (unused-argument)

Thanks for the report - I made a typo and added extra "$" (to the code that handles special syntax with $variable) and this lead to this unexpected bevahour.
