list - Create a list
<H3><A NAME="M3">SYNOPSIS</A></H3>
<B>list </B>?<I>arg arg ...</I>?<BR>
<H3><A NAME="M4">DESCRIPTION</A></H3>
This command returns a list comprised of all the <I>arg</I>s,
or an empty string if no <I>arg</I>s are specified.
Braces and backslashes get added as necessary, so that the <B>index</B> command
may be used on the result to re-extract the original arguments, and also
so that <B><A HREF="../TkCmd/eval.htm">eval</A></B> may be used to execute the resulting list, with
<I>arg1</I> comprising the command's name and the other <I>arg</I>s comprising
its arguments. <B>List</B> produces slightly different results than
<B><A HREF="../TkCmd/concat.htm">concat</A></B>: <B><A HREF="../TkCmd/concat.htm">concat</A></B> removes one level of grouping before forming
the list, while <B>list</B> works directly from the original arguments.
For example, the command
<PRE><B>list a b {c d e} {f {g h}}</B></PRE>
will return
<PRE><B>a b {c d e} {f {g h}}</B></PRE>
while <B><A HREF="../TkCmd/concat.htm">concat</A></B> with the same arguments will return
<PRE><B>a b c d e f {g h}</B></PRE>
