       Tcl_Concat - concatenate a collection of strings

       #include <tcl.h>

       char *
       Tcl_Concat(argc, argv)

       int	    argc	       (in)	 Number of strings.

       char	    *argv[]	       (in)	 Array	of strings to concate‐
						 nate.	  Must	  have	  argc

       Tcl_Concat  is a utility procedure used by several of the Tcl commands.
       Given a collection of strings, it concatenates  them  together  into  a
       single  string,	with  the  original strings separated by spaces.  This
       procedure behaves differently than Tcl_Merge, in that the arguments are
       simply concatenated: no effort is made to ensure proper list structure.
       However, in most common usage the arguments will all  be	 proper	 lists
       themselves;   if	 this  is  true, then the result will also have proper
       list structure.

       Tcl_Concat eliminates leading and trailing white	 space	as  it	copies
       strings	from  argv  to	the result.  If an element of argv consists of
       nothing but white space, then that string is  ignored  entirely.	  This
       white-space  removal was added to make the output of the concat command

       The result string is dynamically allocated using Tcl_Alloc;  the caller │
       must eventually release the space by calling Tcl_Free.		       │
