A quoted name that runs on into a title; .xNNN/.zNNN volumes

"lois 1258 Billy Joel - Extremes.part01.rar lois 1258 Billy Joel - Extremes ",
"GrooveCoverage.part26.rarGrooveCoveragebestof", "Goga Sekulic.part134.rar -
Goga Sekulic - …": the stem kept the title, and each part was a release of its
own (lois, CPP, DieViper, Maveri, tigra: ~2,400 files). runOn cuts the name
after its archive extension when a space, a dash or the name's own start
follows. And three-digit .x/.z volumes ("Reply 987986177631730.x004"),
not .x264/.x265.
