The ArcanistTextLinter currently detects all tab literals and warns about them. Our project uses tabs for indentation (and spaces for alignment), so we need to disable the LINT_TAB_LITERAL rule.
However, this has an inconvenient side effect: the LINT_TRAILING_WHITESPACE rule only checks for trailing spaces, not tabs, so disabling the tab check also prevents Arcanist from detecting trailing tabs.
Reproduction steps:
With the following .arclint, a trailing tab in a file will be ignored. They shouldn't be, since the trailing whitespace rule is not disabled.
{ "linters": { "text": { "type": "text", "severity": { "2": "disabled" } } } }
