Updates to “Automatically removing widows and orphans with lua-widow-control”, TUGboat 43:1

Abstract

I cannot remember where I found the term “club line”. Evidently the books that I scoured in 1977 and 1978 had taught me only that an isolated line, caused by breaking between pages in the midst of a paragraph, was called a “widow”; hence TEX78 had only “\chpar4” to change the “widowpenalty”. Sometime between then and TEX82 I must have come across what appeared to be an authoritative source that distinguished between widows at the beginning of a paragraph and orphans or club lines at the end. I may have felt that the term “orphan” was somewhat pejorative, who knows? 1369
