DESCRIPTION
     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 dif-
     ferently 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 cleaner-looking.

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