For C code, if you have really deeply nested code, sometimes it's better to have some lines which are longer than to have gratuitous line break just to keep everything under 72-76 characters. But if you are writing a block of text, and you are expecting people to read it in a terminal window, I think it is adviseable to wrap at 72 characters. In fact, some will advise wrapping earlier than that, to better aid comprehension. For example: "Optimal line length or column width for body text is 40–70 characters. When people read, their eyes jump across a line of text, pausing momentarily to take in groups of three or four words. Studies have shown that readers can make only three or four of these jumps (or saccades) per line before reading becomes tiring. Too long lines with too many words also make it harder for the eyes to find the correct spot when they sweep back to the left to pick up the next line of text. To maintain readability, it is imperative to use moderate line lengths within the range of 40–70 characters. Do not set normally sized body text in a single column across a 8.5 by 11 inch page. If you do that, the result will greatly exceed 70 characters, reading efficiency will be significantly reduced, and your readers’ attention will be easily lost. Two column layouts are the best solution for achieving optimal body text column widths on American letter size paper. If that is not practical and using only one column is necessary, then be sure to use large side margins in order to bring the line length as close as possible to 70 characters or less." -- https://winterpm.com/ Cheers, - Ted
