concat - Join lists together
<H3><A NAME="M3">SYNOPSIS</A></H3>
<B>concat</B><I> </I>?<I>arg arg ...</I>?<BR>
<H3><A NAME="M4">DESCRIPTION</A></H3>
This command treats each argument as a list and concatenates them
into a single list.
It also eliminates leading and trailing spaces in the <I>arg</I>'s
and adds a single separator space between <I>arg</I>'s.
It permits any number of arguments. For example,
the command
<PRE><B>concat a b {c d e} {f {g h}}</B></PRE>
will return
<PRE><B>a b c d e f {g h}</B></PRE>
as its result.
<P>
If no <I>arg</I>s are supplied, the result is an empty string.
