This module contains *integration* tests. Their purpose is to test the CLI
interface. Namely, that passing a flag does what it says on the tin.

Tests for more fine grained behavior (like the search or the globber) should be

// for really long "lines." The memory map searcher has no need to worry about
// such things, and more than that, it would be pretty hard for it to match
// the semantics of streaming search in this case.

// Binary files with lots of NULs aren't really part of the use case of ripgrep
