_________________________________________________________________DESCRIPTIONTcl_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
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. │
