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

DESCRIPTION
       TTccllCCoonnccaatt  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 TTccllMMeerrggee, 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.

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

       The result string is dynamically allocated using TTccllAAlllloocc;  the caller |
       must eventually release the space by calling TTccllFFrreeee.                  |
