d2824f5294 Revert "Do not use arg.h for tools which take no flags" 
This reverts commit 9016d288f1.

Tools that have no options are required by POSIX to support "--" so
that conforming applications have a way to shield their operands from
implementations that provide options as an extension.

echo(1) is just an exception, so it is handled specially.

See OPTIONS in https://pubs.opengroup.org/onlinepubs/9699919799.2018edition/utilities/V3_chap01.html#tag_17_04

01b5105e0c mkfifo: Simplify -m handling 
Rather than create the FIFO with incorrect permissions at first, then
restore with chmod(2), just clear the umask when -m is specified, and
pass the parsed mode to mkfifo(2).

09c2311b3a date: Fix default format string 
From POSIX:

When no formatting operand is specified, the output in the POSIX
locale shall be equivalent to specifying:

99c7876310 On glibc, include sysmacros.h directly 
On glibc, major, minor, and makedev are all defined in
sys/sysmacros.h with types.h only including this for historical
reasons. A future release of glibc will remove this behaviour,
meaning that major, minor, and makedev will no longer be defined
for us without including sysmacros.h.

f45156d5b4 Simplify expression in makeline() 
This expression was wrong, but it was causing a false positive
in some compilers that couldn't see that error() cannot return.
The actual problem of the line is that it was too complex and it is better
to split it in simplex expressions.

4b9c6645f5 sed: Fix parsing bug in find_delim 
's/[[x=]//' was parsed as 's/[[=x]//' which (correctly)
raises an error because the "second delimiter is missing", here =].

The two got mixed up because the parser didn't return to
the "inside bracket"-state after encountering an opening bracket
while inside the bracket expression.
