The Lua(Meta)TeX manual mentiones that \leftghost and \rightghost come from Aleph. I searched the web quite a bit about Omega and Aleph on that issue, and tried other things, but found nothing of relevance. There is a manual for Omega, but, after conversion from ps to pdf, and opening the pdf with Evince, the search function did not find the phrase 'ghost' in it, either. i'm going to remove it ... we have plenty of ways to prevent ligatures and influence kerning and context nowhere uses it anyway
