Subject: This patch series changes everywhere the back-quotes construct for
 command substitution with the $( ... ).
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The backquoted form is the historical method for command substitution,
and is supported by POSIX. However, all but the simplest uses become
complicated quickly. In particular, embedded command substitutions
and/or the use of double quotes require careful escaping with the backslash
character. Because of this the POSIX shell adopted the $(…) feature from
the Korn shell. Because this construct uses distinct
opening and closing delimiters, it is much easier to follow.
Also now the embedded double quotes no longer need escaping.
