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.
