//! Without `-o`, `convert` writes beside the input into a directory named by the
//! input's stem *and* extension.
//!
//! With the stem alone, `A2.docx` and `A2.pptx` shared one directory and the second
//! conversion silently overwrote the first one's files. The DOCX is built here so the
//! test carries its own fixture.
