The lone-dash check read MAME's -rompath and -samplepath, QUASI88's
-romdir and RetroBat's -hash and -sp as half a dash glued to a word.
Quoted as code they read as flags. A C loop quoted in romdir.py and a
docstring in test_agnostic_scope no longer read as clause semicolons.
validation: [romdir] walks a PS2 ROM directory the way the profile's
fork reads it, masked_sha1 hashes a file with a byte range cleared, and
size_multiple bounds a size to a granule. The resolver name steps, the
pack and manifest scans, the emulator expansion and verify call the same
content_fits. A PCSX2 companion is taken only beside an image that
passes, and a companion placeholder no longer seeds a scan of its own.
