robotidy --separator tab does not respect tabs in Settings

[antonvw]

When using robotidy on robot framework file that has a Settings section containing tabs, it replaces tabs with space even if --separator tab is used.

Thanks for the report, I will investigate it.

I can reproduce it and I will fix it - robotidy should respect tab separator. Though since we mostly focus on space support it's the issue for most of our transformers. For example following variables section will be also formatted to use space regardless of separator value:

*** Variables ***
${SHORT}	a
${LONG_VARIABLE_NAME}	b

I can add some tests to see to catch and fix those issues, but feel free to report similar cases.
