[tex-k] Answers to 14.23 and 14.24 in The TeXbook

[Ruixi Zhang]

Apologies for my editorial errors---one shall not make a report hours into midnight.

The relevant lines are on pages 315 and 316 (not 311 and 312, how embarrassing! sigh...). Fortunately, the exercise numbers 14.23 and 14.24 were correct.

More on p. 315, line -3: If changes were to be made and if an extra line were to appear, the extra line would more likely fit onto this page rather than onto the next. (I counted 14 vskips on p. 315 and 12 vskips on p. 316.)

More on p. 316, line 7: Although technically not necessary, it is perhaps better also writing a comment char after closing the edef, that is, '\edef\next{\prevgraf=\the\prevgraf\space}%' or '\edef\next{\prevgraf=\the\prevgraf\relax}%'. (This '%', unlike the first one for line 5, is unnecessary since TeX ignores spaces in vertical mode. Adding it is simply for the sake of consistency with line 5.)
