remove "bam dang po", etc. at the end of works (and recluster)

[eroux]

see WA0XL9ED737B1E5C6 for instance

let's try pod dang po, bam 1, pod 1, etc. too

and also " bzhugs so", "zhes bya ba" (/ces bya ba) and the end, "'phags pa" at the beginning

and also remove initial 1)_ at the beginning like in https://www.tbrc.org/xmldoc?rid=O1PD107142 , that also has the case "ka1)_", etc.
