A few programs used the plural in their synopsis which doesn't read as
clear as the obvious triple-dot notation.
mdoc(7) .Ar defaults to "file ..." if no arguments are given and consistent
use of 'arg ...' matches that behaviour.
Cleanup a few markups of the same argument so the text keeps reading
naturally; omit unhelpful parts like 'if optional arguments are given,
they are passed along' for tools like time(1) and timeout(1) that obviously
execute commands with whatever arguments where given -- just like doas(1)
which doesn't mention arguments in its DESCRIPTION in the first place.
For expr(1) the difference between 'expressions' and 'expression ...' is
crucial, as arguments must be passed as individual words.

When the input to csplit contains fewer lines than the number of matches
specified, extra output was mistakenly included in some output files.

Patches from Jan Stary <hans at stare dot cz>, tweaked by me and tb@.
While here, apply some simple style improvements:
Sort headers, static void __dead usage(), return from main(),
zap case '?', drop /* NOTREACHED */, drop break after usage(), ...

the newfile() function used for create files open files in "w+"
(O_RDWR), and may occasionally do reading on the file (function
toomuch()).
