Because we reuse `-new-window` for Taskbar Tabs shortcuts for fallback when Taskbar Tabs are disabled, `command-line-handler` was modified from `m-taskbar-tabs` to `l-taskbar-tabs` to ensure we preempt `BrowserContentHandler` which consumes `-new-window`. As a tagalong, fixup Unix style line endings. Differential Revision: https://phabricator.services.mozilla.com/D249722
