Under each method, its extensions (Q CS XT Z ZZ IB W U): bold and ticked, it exists; struck, it does not. The extensions and what they mean

Examples: 0 come from the library's tests; 22 were composed from each method's signature and run for this page, on a fresh object, for example cDup = "aaa" + NL + "bbb" + NL + "aaa" o1 = new stzStringLines(cDup). 7 methods have none yet.
