Use ISO-date-format in manpages The one specified by mdoc is hard to read for non-native speakers from countries which read the date day-first (like Germany, Greece, North-Korea, Swamp,...). This is also consistent with how we generally specify dates at suckless.org. 2015-10-08 15:15:08 +00:00			`.Dd 2015-10-08`

Fix various lint warnings in manuals Fix "new sentence, new line" warnings throughout so that formatters can produce correct spacing between sentences. join.1 Remove unnecessary Ns macros. These are not necessary for delimeters, which get special treatment. xinstall.1 Fix date in manual. The contents were last modified on 2016-12-03, so use that instead of the invalid date. grep.1 Fix escape sequence for `\<` and `\>`. ed.1 Remove spurious `\\n` escape for the null-command. 2020-03-01 22:37:31 +00:00			`file.`

POSIX 2013 audit Mostly manpage-shuffling according to the changes in the corrigendum, wording changes and more idiomatic expressions. All this is finished up by marking the POSIX 2013 conformant tools with .St -p1003.1-2013 which is not available in older mandoc builds or nroff, but which reflects what we actually did, so who cares? This is a huge step and it's not far until we can release sbase 0.1. 2015-03-27 16:22:48 +00:00			`.St -p1003.1-2013`
